TEST: Black Lion Audio B172 MKII

And once again Neve, or should we say "Inspired By Neve", because the American company Black Lion attaches great importance not to be called a clone. With the Black Lion Audio B173 MKII, the company now presents the update of the MKI version, which differs in only a few, but crucial points.

MKI versus MKII

As always with an update, the user is of course primarily interested in what has changed compared to the previous model. Apart from a different color scheme, I couldn't find any differences at first glance. I admit, I also had to contact the German distributor first to find the exact differences between the MKI and MKII versions, especially since I had not yet had the MKI version in my fingers. Here is the result of the research:

1.) First, the layout of the product has obviously been changed from the really "borderline" blue / black to a uniform black, which puts the device in the new uniform appearance of the Black Lion preamps.

2) An additional output transformer was integrated, so that the preamplification could be raised up to 70 dB and the noise component could be lowered again.

3) Probably the most important point of the update, which many users have been waiting for, the retail price has been reduced from 626 € to 539 €.

All in all, there are several good reasons to take a closer look at the MKII version.

The concept of the Black Lion Audio B173 MKII

As already mentioned, the company with its headquarters in Chicago leans with the Black Lion Audio B173 MKII strongly on the concept of the Neve 1073, which is probably the most copied preamplifier par excellence. The product is built in a half rack unit, a format that has recently gained significant acceptance in the recording studio sector. However, for those who would like to use the product in standalone mode outside of rack operation, an appropriate base is recommended. Although the bottom of the Black Lion Audio B173 MKII has no sharp edges or screws, the product does not come with rubber feet or similar coasters.

The entire presentation of the product is extremely massive, which is also reflected in the comparatively high weight of the product of just under 1.4 kg. The likewise "spatially expansive" power supply is unfortunately installed externally, which leads us to the usual "where-with-the-bump" department and is probably owed to the comparatively low selling price. Yes, there are two drill holes in the PSU's plastic casing to screw the hulk under the tabletop or similar, but practicality is unfortunately different.

Of course, there is the assessment that the available budget has been shifted in favor of high-quality components and the red pencil has been better applied to the power supply, but be that as it may, anyone who uses several sound components with external power supplies in their studio knows the eternal search for the appropriate storage location. At least the plug on the back of the case, which rests against the case, grips properly and cannot be pulled out of the case so easily by mistake.

Otherwise, the preamp presents itself like its predecessor, i.e. the front panel is dominated by a large gain control with 5 dB steps and a smaller, non-gridded output control. A mini-switch acts as an On / Off switch, while three small pushbuttons can be used to switch on 48 V phantom power, rotate the phase or activate the high-impedance input on the front panel. The On / Off mode, the phantom power and the Hi-Z input have been provided with an LED control light for status checking. Despite the sleek layout, the product exudes a touch of vintage character, which is due in particular to the control knobs, they take on the vintage charm of past eras and could therefore easily come from a military movie of the sixties, good grip and solid feel included.

The three LEDs really have it going on in terms of luminosity. All three shine in a brilliant white, whereby "brilliant" is still to be described as discreet. Personally, the indicators "bite" a bit too hard in direct visual contact, but this is by no means meant to be a rating, but merely describes my personal taste. Different colors would do the clarity good, but would probably reduce the visually uniform image in their homogeneity somewhat.

On the rear, the product has an XLR input, as well as a balanced TRS output. Likewise, there is an internal chassis ground in case of occurring ground hum, as well as the plug for the external power supply. The aforementioned high-quality internal components include a CineMag input transformer and an Edcor output transformer, with the discrete design operating in Class A mode.

The Black Lion Audio B173 MKII in practice

First of all, let's move on to one of my favorite topics, the haptics. Here, in addition to its already mentioned solid construction, the product also shines with well-fitting push switches, high-quality potentiometers and firmly gripping sockets. It is simply fun to touch the Black Lion Audio B173 MKII.

Regarding the operation, there is not really much to do wrong with only 2 controls, but both have a massive impact on the final sound material, depending on the control settings. As sound examples I have deliberately chosen sparsely structured sound material to be able to present the compression of the source material as intensively as possible.

Now then, how does the Black Lion Audio B173 MKII sound. Simply put, it sounds as you'd expect it to sound, and in the best sense of the word. Entirely rooted in the Neve empire, the product colors the adjacent sound material very intensively, but without copying the Neve sound 1:1. The Black Lion Audio B173 MKII has, despite the Neve cuddling course, a clearly independent sound behavior, which is reflected in particular in the saturation. But everything nicely one after the other.

The first thing that catches the ear is the soft basic sound of the preamp. As with its forefather, the Black Lion Audio B173 MKII manages an optimal symbiosis of subtle compression and a tasteful lowering of the high mids, which flatters the human ear in more ways than one. If you listen to the original recordings of the sound samples and compare them with a linear recording via the preamp, the sonic differences are eminent. The product succeeds in making almost every applied sound material sound a tad "finer", "softer" and "more expensive".

In this regard, the B173's treble in particular makes it a good choice for adding a bit more "brightness" to dull signals or recording instruments that often need a top-end boost.

However, the real bonus point of the product reveals itself when you leave the "clean" paths and you move into saturation. Here, the Black Lion Audio B173 MKII can show a strength that makes the analog signal processing area really interesting. Especially impulsive signals such as drums or percussion instruments benefit from the mixture of compression, overtone enrichment and general sound compression, which comes close to an overdrive pedal, as long as you don't overdo it, or if you are in the experimental area, really overdo it.

The result is a rich sound, which of course polarizes, but in the mix significantly reduces the need for a compressor, or its efficiency, especially in the threshold due to the compacted sound material can be set significantly higher. Especially in the analog range, for example with drum machines or vintage drums, such a sound is almost obvious. Here it becomes clear once again that the Black Lion Audio B173 MKII is not a pure clone of a 1073, but generates an independent sound image.

Of course, this sound effect is old hat, but between the audiophile design are partly worlds. Depending on the circuit and component quality, you can choose between scratchy, undynamic half-wave cut or a smooth transition that allows a range from magnetic tape saturation to tube-like overdrive to tangible distortion. The Black Lion Audio B173 MKII definitely belongs to the second guard, but it convinces with a very musical, practical saturation process, which is convincing in many instrument genres.

Conclusion

With the Black Lion Audio B173 MKII, the American manufacturer has a Neve homage in its ranks that has it all. The preamp, which is oriented on the 1073, convinces with a high-quality workmanship, an excellent sound and an excellent saturation effect, which also conveys wacky sound ideas in high-quality.

In addition, the MKII version has a more visually appealing appearance, an additional output transformer and has been reduced in price by about 15% compared to the MKI version.

A truly attractive offer, definitely test once.

- The Neve 1073 is a legendary analog preamplifier and equalizer that has become an industry standard in the world of professional audio recording. Originally designed by Rupert Neve in the early 1970s, the 1073 was featured in Neve's A88 console and quickly became a favorite among recording engineers due to its warm, musical sound and versatile EQ.

The 1073's preamp section features a Class-A design with a discrete transistor circuit, which contributes to its rich and creamy sound. The preamp has switchable mic/line inputs, as well as a high-pass filter and a switchable 48V phantom power for condenser microphones. The preamp can add up to 80 dB of gain, which makes it suitable for recording a wide range of sources, from quiet acoustic instruments to loud rock bands.

The 1073's EQ section is also highly regarded, with three bands of equalization that allow for precise tonal shaping. The low-frequency band has a selectable frequency of 35 Hz, 60 Hz, 110 Hz, and 220 Hz, and can boost or cut up to 18 dB. The mid-frequency band has a selectable frequency of 360 Hz, 700 Hz, 1.6 kHz, 3.2 kHz, 4.8 kHz, and 7.2 kHz, and can boost or cut up to 16 dB. Finally, the high-frequency band has a selectable frequency of 10 kHz and 12 kHz, and can boost or cut up to 18 dB. The EQ section can also be bypassed entirely if desired.

One of the key features of the 1073 is its ability to impart a desirable coloration to the sound. The preamp and EQ circuits are designed to add subtle harmonic distortion and saturation, which can help to warm up and thicken the sound of recorded instruments and vocals. This character has become a signature sound of the 1073, and many modern emulations and clones seek to replicate this sonic character.

In addition to its sound quality, the 1073 has become famous for its build quality and reliability. Neve's original units were built to withstand the rigors of professional studio use, and many vintage 1073s are still in use today. Neve's modern reissues and clones continue this tradition, with high-quality components and meticulous attention to detail in the manufacturing process.

Over the years, the 1073 has been used on countless classic recordings by artists such as The Beatles, Pink Floyd, Led Zeppelin, and Nirvana, among many others. Its warm, musical sound and versatile EQ have made it a favorite among recording engineers across genres, from rock and pop to jazz and classical. Today, the 1073 remains a highly sought-after piece of studio gear, and its legacy continues to influence the sound of modern recordings.

TEST: Blackstar Silverline Deluxe Head

Large, sensitive and above all heavy, almost all all-tube amplifiers in the world have been presenting themselves for almost 6 decades now, not forgetting that they were and are the icing on the cake of the sonic phallic symbol of every full-stack. However, as is generally known, times are changing and hardly any guitarist today is still willing, for sound reasons, to heave a corresponding head, possibly still packed in a flight case for transport reasons, to the next club gig, only to hear both from colleagues and the FOH repeatedly that he was once again much too loud on stage. Those who would still like to know the ultimate look of rock'n'roll on stage, but without having to lift the corresponding weight, definitely belong to the target group of the Blackstar Silverline Deluxe Head, which sonically prepares to emulate the familiar as well as possible and present modern.

The construction of the Blackstar Silverline Deluxe Head

The Blackstar Silverline Deluxe Head is sometimes touted as a single-channel hybrid amplifier, which is misleading in several respects. On the one hand, with the combination of digital preamplifier and analog power amplifier, a tube often used in the hybrid range is looked for in vain in the signal path and the so-called single-channel on the other hand has up to 128 memory locations, which can be managed via the optionally available FS-10 footswitch, or a MIDI bar. The weight of just under 23 kg is, as expected, primarily based on the wooden construction of the housing, the internally installed transistor technology is, in contrast to the weight-driving components of the all-tube amplifiers, especially in the form of input, output and power transformers, only responsible for a minimum weight and could easily be accommodated in a fraction of the housing dimensions.

Visually, the Chinese-built Blackstar Silverline Deluxe Head presents itself in a vintage-like look of gray and silver, which goes a little in the direction of the current Sound City amps. It does not lack a certain charm to lay out optics and technology as diametrically as possible. In terms of dimensions, the head is slightly smaller than the classic Marshall briquette and is in the range of the Rectifier Heads. In terms of workmanship, there are no points of criticism, although the knobs and push buttons have a touch of play and indirectness, which lack the classic "massive" of an all-tube head, although this should be the target audience probably quite "latte". The head brings a power of 100 watts at 4 ohms, which decreases as with all transistor amplifiers with increasing number of ohms, so that the amp at 8 ohms still has about 50 watts and at 16 ohms just under 25 watts of power. From there, with a large stage and the use of 412er Cabinets is to be made certain that the box has a 4 ohm input, old Mershall Mono Cabinets could make one with their 16 ohms a line through the acoustic calculation.

Interesting is the choice of words of the modeler, which avoids the association to the blueprints of the classic sounds and only falls back on already established terms for some innocuous details. For example, the digital preamp is called "Voicings", which are divided into Warm Clean, Bright Clean, Crunch, Super Crunch, OD 1 and OD 2. To be honest, I personally like these names much better than the sometimes rather embarrassing names of some competing products, which for example come up with "Fander", "Saldona" or "Marhall".

In addition to the typical 3-band tone control in the preamp and the resonance and presence controls in the power amp, Blackstar relies on two additional tone controls that go beyond the usual level of sound management. First, the Brits have built their ISF circuit into the Blackstar Silverline Deluxe Head, which is supposed to allow seamless blending between an "American sound" (designed to be more scoop-heavy) and a "British sound" (mid-peak). Of course, it's not possible to crossfade between a Twin Reverb and a JMP using a single knob, but you can set your preferences in advance.

As a special feature, however, the amp has a selector switch, which emulates the sound and resonance behavior of the most common power tubes (EL84, KT66, 6V6, 6L6, EL34 and KT88) and should thus provide more tonal variety. In order to be able to offer at least a rudimentary stand-alone solution in terms of FX, the amp has a simple internally installed multi-effects unit, similar to the Grandmeister and BS200 series from H&K, which pre-selects modulation, delay and reverb using a rotary control and then adjusts the intensity with a level control. If one wants to use appropriate effects, this is unfortunately the only possibility selbige to use, over a serial FX loop, which permits it to place straight room effects such as delay or reverb between preamp and output stage, does not exist. Perhaps a useful addition for the MKII version.

The rear panel of the Blackstar Silverline Deluxe Head is simple and appropriate to the concept of the head. In addition to the two footswitch inputs, the amp offers a TRS input for feeding external sound sources such as an MP3 player and it offers a frequency-corrected output for demo recordings or for all users who want / need to do without a miked pickup of the guitar, a direct feed into the P.A..

In practice

Despite the many setting options, you can quickly find your way around the front panel of the Blackstar Silverline Deluxe Head. First a basic sound selected and then roughly with the ISF controller its preferred alignment selected. One point is already noticeable with the first tones that flow out of the speaker, the amp was not primarily designed for clean sounds. The sound files were recorded with a Les Paul Standard, whose burstbucker pickups have a truly moderate output and yet the gain control had to be turned down to near zero to achieve a more or less clean sound. Despite this setting, the one or other saturation occurred under hard attack, but ultimately all not bad, older JCM have not managed this and in a pinch there is always the volume control on the instrument.

The focus of the Blackstar Silverline Deluxe Head is of course on the power tube simulations, which makes the amp in this price range clearly stand out from the field of competitors. I therefore recorded all sound files with the different power amp simulations one after the other to demonstrate the sonic differences. The amp was connected to a H&K Oversize 412 Cabinet with Celestion Lead 80 speakers, recorded with a Fame MS57.


If you take the 6 different voicings and combine them with the 6 different power tube emulations, the whole thing still in combination with the ISF control, results in a very high sound yield for the amp indeed. Thereby everything is present from cutting sharp to pumping fat, which one would like to call on the plan at sounds. Especially in the high gain range, which basically starts at Super Crunch, the amp offers many possibilities to determine your preferred sound. However, all sounds seem to derive their diversity from different EQ settings in the presets, less from the complex interaction of the individual components, as is the case with a tube power amp. Of course, at a retail price of less than €500, no one will have expected a perfect representation of the individual tube parameters, and in some combinations you can also very nicely make out the different characteristics of the individual tube emulations in direct comparison, but it remains an emulation, albeit an ambitious one.

Only one point makes me think, although it is well thought out by the designers. The respective power tube emulations are programmed in the comparison in the approximate volume, which they also deliver in the original, that is, the EL84 simulation is for example many times quieter than a KT88 simulation. Well thought, but there is with the personal programming of the sounds this accordingly to consider. One can also understand the different volumes well in the sound files.

Sonically, the amp is quite convincing, especially at lower volumes, although with a slightly busy basic sound, it sometimes has some problems to assert itself in the band context. But if you keep your drummer on a tight leash and hide the 8x10 cabinet from the bass player, you should be able to handle it ;-)

Conclusion

With the Blackstar Silverline Deluxe Head, the British manufacturer has a sonically flexible and visually appealing head on the market. The amp offers a wide range of sounds through 6 different voicings, 6 power tube emulations and Blackstar's own ISF circuit, which score especially in gain and high gain. If you want to shine visually on stage without having to transport an all-tube head, you should test the head once.

- Guitar amplifier heads, or topteile in German, are an essential component of any electric guitar setup. They are responsible for amplifying the signal from the guitar and shaping the sound to the player's liking. In this article, we'll take a closer look at guitar amplifier heads, their features, and why they are such an important piece of gear for guitar players.

First, let's define what a guitar amplifier head is. It is essentially the main component of a guitar amplifier, consisting of the preamp, power amp, and sometimes the effects loop. The head is connected to a separate speaker cabinet that contains the speakers and provides the sound projection.

One of the main advantages of using a guitar amplifier head is the flexibility it offers. Players can mix and match different heads and cabinets to achieve a variety of tonal possibilities. For example, a player may choose a vintage-style head paired with a modern speaker cabinet to create a unique sound.

Guitar amplifier heads come in a range of sizes and power ratings, with options available for everyone from bedroom players to professional musicians playing large stages. The power rating of an amplifier head is measured in watts and determines the volume and headroom of the amplifier. Higher wattage heads are capable of producing louder volumes and can handle larger speaker cabinets.

Many guitar amplifier heads also come equipped with features such as multiple channels, built-in effects, and EQ controls. These features allow players to dial in a variety of tones and customize their sound to their liking. Some heads also feature built-in attenuators, which allow players to reduce the volume of the amplifier without sacrificing tone.

When choosing a guitar amplifier head, it's important to consider the type of music you'll be playing and the venues you'll be performing in. If you're a bedroom player or only play small gigs, a lower wattage head may be suitable. For professional musicians playing larger venues, a higher wattage head may be necessary to achieve the desired volume.

There are many reputable guitar amplifier head manufacturers to choose from, each with their own unique sound and features. Some of the most popular brands include Marshall, Fender, Mesa/Boogie, Orange, and Peavey.

In conclusion, guitar amplifier heads are an essential component of any electric guitar setup. They offer flexibility and customization options, allowing players to achieve a variety of tones and sounds. When choosing a head, it's important to consider factors such as wattage, features, and your specific needs as a player. With the right head and speaker cabinet combination, guitar players can achieve the sound they've been searching for.

TEST: Beyerdynamic T1

 There are no longer many traditional German companies, which had and have the staying power within the music business against the mostly Asian competition. The "Made in Germany" label, which was actually intended as a devaluation when it was introduced and is now obligatory in terms of quality, is unfortunately always accompanied by corresponding manufacturing and ancillary wage costs, so that many manufacturers have gone over to developing in Germany but having it completely manufactured in China. One of the few exceptions is the Beyerdynamics company from Heilbronn, which, with very few exceptions, has everything from development to final production done in Germany and has a real battleship in terms of headphones on offer with the Beyerdynamic T1.

A retail price of just under 1,000 Euros then also addresses the targeted clientele right away. It's unlikely that a budget or home studio owner will spend such an amount on a product that experience has shown to be indispensable for work, but which can only be operated in conjunction with one or more monitor systems. Do I hear the first voices that mix only through headphones? Or are there even some who, in cooperation with the SPL Phonitor, have consciously decided against near-field monitors? The same should read the following lines very meticulously, it could pay off economically.

Concept

We all know headphones and earphones from various fields of application. Primarily, everyone will have the classic image of the acting musician in the recording room in front of him, while the sound engineer together with the producer sits in the control room in front of the monitor. In times of flexibility and mobility, however, the trend towards high-end headphones is clearly on the rise. Whether for a silent session, while traveling, or as a second or third monitor, the importance of a serious alternative to a near-field monitor has grown steadily in recent years, not to mention the loyal community of hi-fi enthusiasts.

With the Beyerdynamic T1, the Heilbronn-based company presents the top model of its Tesla series, which are newly developed transducers with a drive power of over one Tesla (unit of measurement for magnetic flux density) for higher efficiency.


Design

The Beyerdynamic T1 uses a semi-open design, as found on its sister model, the DT 880 Pro. It is a dynamic headphone where the ear cups are completely enclosed. The overall appearance of the Beyerdynamic T1 can be considered downright classy. The color combination, which ranges from matte silver to classic black, combined with solid-looking speaker mounts and absolutely impeccable workmanship flash German engineering skills not only at first glance.

Compared to many competitors, the included cable has the rather rare double cable routing, which leads to a more even pull on both halves of the head, if one can speak of pull at all. Both earpiece cable plugs are pluggable and gold-plated, on the other side there is a likewise gold-plated 6.35 mm plug, which can also be reduced to 3.5 mm minister stereo jack by means of a screw connection. In order to protect the cable ends during transport or generally in the unplugged state, there are a total of 3 plastic sleeves over the cable, which can be pulled over the plug ends if necessary.

Even though the mini-jack operation would be ideal for mobile devices, the comparatively high impedance of 600 ohms restricts the direct use considerably due to the significantly lower maximum volume. In order to be able to feed the headphone in high quality according to its design, a serious headphone amplifier has to be used. On the other hand, those who are willing to spend a four-digit amount for a top headphone will almost certainly also own a corresponding amplifier. The Beyerdynamic T1 is transported in a sturdy yet very light hard case, which fits the headphones and cables perfectly.



Open, semi-open, closed

According to the product description, the Beyerdynamic T1 is described as semi-open headphones, which implies a reduction of sound in both directions (inside out, outside in). I honestly cannot comprehend this designation, as there was in fact no reduction of ambient noise once the headphones were put on. The headphones are rather to be understood as open headphones, but this does not negatively affect their use on the desk in any way. Only for use in the recording room is this design a disadvantage, but the Beyerdynamic T1 was not designed for this purpose.


Wearing comfort

Once the earpieces have been optimized for the shape of the head, it's only the headband and the ear pads that can reduce the wearing comfort of the headphones. Here, the Beyerdynamic T1 positively stands out from the list of competitors. The headband, covered in protein-coated leatherette, rests very softly on the head, with the large velour ear pads clinging to the sides of the head in an almost impalpable way. The result is a headphone that, despite weighing 356 grams (without cable), feels seemingly weightless and yet fits securely on the head. Highest perfection in wearing comfort.

Even after several hours of wearing, no fatigue of the head could be determined. The effect of the massive, but also comparatively heavy cable is debatable. Some colleagues complained about a certain tensile load if you let the cable slide to the floor in its entire length, which only decreases as soon as you move the cable relatively close to the headphones, for example as a relief over the work desk. I can't share this assessment. In my opinion, the stiffness of the cable provides a cushioning of the tensile load more like a flexible stick when it is placed on the floor. However, everyone should form their own opinion here, especially since the demands on one's own workstation vary greatly from person to person.


Sound behavior

If you look inside the ear pads, you can see that the respective sound transducers have been positioned slightly slanted towards the front. Whether this is due to the natural shape of the ear or to prevent the extreme stereo image of headphones remains a secret of the engineers, but the fact is that the Beyerdynamic T1 delivers excellent performance in terms of spatial imaging. The depth gradation is impressive for a headphone, which increases even more with a special headphone amplifier with crossfeed setting, such as the SPL Phonitor series.

At the same time, the coloration of the sonic material remains very subtle. The bass range remains tight, dry and transparent even with strong impulses, the midrange linear and analytical, far from the scoop characteristic of those products that want to offer the ear a still non-existent euphony. Only the treble reproduction shows a discreet overemphasis, which should be considered especially in high-gain guitar-heavy productions.

The Beyerdynamic T1 also sets new standards in terms of impulse response. The aforementioned Tesla technology with its ultra-fine voice coil contributes significantly to this sound behavior. The material used is extremely fast in conversion and thus ensures a fine and ultra-compact response.


Conclusion

With the Beyerdynamic T1, the traditional company from Heilbronn has a pair of headphones of the absolute top class on the market. In terms of workmanship, the product scores points across the board in terms of design, construction, wearing comfort and especially sound. The high impulse fidelity of the product and its excellent spatial resolution sometimes reveal subtleties in the sound material that can be lost even in a high-quality near-field monitor.

Equipped with tight and dry basses, linear mids and a clear treble definition, the Beyerdynamic T1 allows for fatigue-free work, which also invites for expansive sessions due to an outstanding fit. The delivered sound material sounds extremely lively over its entire frequency spectrum without coloring nicely.

An absolute top product in every respect, which leaves only the highest mark!

- Beyerdynamic: A Legacy of Excellence in Audio Technology

Beyerdynamic is a German-based company that has been a leading manufacturer of high-quality audio equipment for over 90 years. Founded in 1924 by Eugen Beyer in Berlin, the company has established a reputation for producing some of the finest headphones, microphones, and other audio equipment in the world.

Early Days

In its early days, Beyerdynamic was primarily focused on creating microphones for use in broadcasting, as well as for public address systems. However, it soon expanded its product line to include headphones and other audio equipment.

One of the company's most significant contributions to the world of audio technology was the introduction of the first dynamic headphone in 1937. This innovation changed the game for music lovers and professionals alike, as it allowed them to experience high-quality sound without the need for bulky and expensive electrostatic headphones.

Post-War Innovations

Headphones: A Comprehensive Guide to the World of Personal Audio

Headphones have become an integral part of our lives, whether we are commuting to work, working out at the gym, or just enjoying our favorite music at home. They provide a personal audio experience that allows us to immerse ourselves in the music and block out the distractions of the outside world. In this article, we will explore the world of headphones, from their history and development to the latest trends and technologies.

History and Development

Headphones were first developed in the late 19th century as a way for telephone operators to listen to calls without disturbing others. Over time, they became more widespread, with early models used primarily in radio communication and broadcasting.

In the 1960s, the introduction of the transistor led to the development of smaller, more portable headphones that could be used with personal music players like the Sony Walkman. This marked the beginning of the modern era of headphones, with companies like Sennheiser, Beyerdynamic, and AKG leading the way in innovation and design.

Types of Headphones

There are several types of headphones available today, each with its own advantages and disadvantages.
Over-Ear Headphones: Also known as circumaural headphones, these are the largest and most comfortable type of headphones. They fit over the ears and provide excellent sound isolation, making them ideal for use in noisy environments. However, they can be bulky and heavy, making them less portable than other types of headphones.

On-Ear Headphones: Also known as supra-aural headphones, these fit on top of the ears rather than over them. They are generally smaller and more portable than over-ear headphones, but they may not provide as much sound isolation.

In-Ear Headphones: Also known as earbuds or in-ear monitors, these fit directly into the ear canal. They are the most portable and lightweight type of headphones, but they may not provide as much sound quality or comfort as other types.

Wireless Headphones: These are headphones that connect to your device via Bluetooth or other wireless technologies. They are becoming increasingly popular due to their convenience and lack of cables.
Noise-Cancelling Headphones: These headphones use active noise cancellation technology to block out external sounds, making them ideal for use in noisy environments like airplanes or public transport.

Choosing the Right Headphones

When choosing headphones, there are several factors to consider, including:
Sound Quality: The sound quality of headphones can vary significantly, so it's important to choose a pair that provides the level of audio fidelity that you require.
Comfort: Since you will be wearing your headphones for extended periods, it's important to choose a pair that is comfortable and doesn't cause fatigue or discomfort.
Portability: If you plan to use your headphones while traveling or on the go, it's important to choose a pair that is lightweight and easy to carry.
Price: Headphones can range in price from a few dollars to several thousand dollars. It's important to choose a pair that fits within your budget but still provides the features and performance that you need.

Conclusion

Headphones have come a long way since their inception, with advances in technology and design leading to a wide range of options for consumers. Whether you are looking for headphones that provide excellent sound quality, portability, or noise cancellation, there is a pair of headphones that will meet your needs. By understanding the different types of headphones and the factors to consider when choosing a pair, you can find the perfect set of headphones to enjoy your favorite music and audio content.

TEST: Sound City Master One Hunderd

 Yes, they still exist! After years of the common league of amp manufacturers primarily focus on the transfer of classic all-tube sounds in the smallest and lightest possible alternatives to the fat all-tube head, the astonishment was great, when I heaved the Sound City Master One Hundred in my studio. The packaging was like its contents, big, heavy, clunky, unwieldy, and contained everything the bulk of amp smiths try to avoid these days. Just unpacking it in itself required an appropriate amount of effort. I like the amp already ;-)

The British Sound Invasion

Sound City? Never heard of it! In fact, you must have left at least 60 behind to still remember this name. Also I have not personally held this amp label in my youth, however, I was always told by the next higher generation of a "Marshall For Pedestrians", which one "could take in a pinch". The company Sound City could not have been described more unqualifiedly, since it was one of the first representatives of the classic British rock sound, together with the companies Marshall, Vox and Hiwatt, at a time when the island was seen as THE navel of the world in terms of music.

In particular, the name Hiwatt is very strongly associated with the trademark Sound City, as founder Dave Reeves celebrated his big breakthrough with Hiwatt a few years later after the introduction of Sound City in the early / mid-sixties. Allegedly, the Sound City amps were easier to import to continental Europe, so that especially in Germany, the name was sometimes more present than the superfather Marshall. Scene greats like Pete Townsend, Marc Bolan and Jimi Hendrix were seen with the Sound City fullstacks, but in the end the commercial skill of Jim Marshall was probably the decisive factor for his omnipresence, which (still) continues to this day.

After Reeves had much more success with "Built-As-A-Tank" Hiwatt models than with Sound City, probably also due to several attitude characteristics, the brand disappeared from the scene for more than 40 years and survived only in the memories of today's grandfathers. Only in 2017, the brand was revived under the leadership of Neil Ostberg and amplifier jack-of-all-trades Steven Fryette, who is already with VHT and his current Fryette amps just in the high-gain area on everyone's lips, and strikes soundwise a diametrically different path than what you're used to from Fryette.

The concept of the Sound City Master One Hundred

Whoever sets out to reanimate a more or less legendary name always faces the same problems. On the one hand, the components of the time are only available in modified form, if at all, and on the other hand, sound and volume tastes have truly changed completely in over four decades. In addition, one fights with many competitors in terms of price, which have been able to gain some advantage in recent years through Asian manufacturing or at least a much stronger trademark.

Aware of this, Fryette relies on a combination of vintage feel, combined with its wealth of experience in terms of sound culture. However, this also means that the current Sound City Master One Hundred is likely to differ significantly from its forefathers in terms of sound, but not without waving the appropriate vintage flag. Let's be surprised.

The construction

The Sound City Master One Hundred is one of those amps that both bandmates and FOH mixers feel a mixture of weak knees and worry about the eternal volume discussion. If the guitar mate doesn't immediately get a load resistor out of his transport box, every experienced musician knows what's in store for a 100 watt all-tube head at the first power chord. A beaming face on the part of the guitarist and desperate shaking of the head on the part of everyone else present, seasoned with the words "it has to be like that, otherwise it won't sound". In the choice of tubes, Fryette has also departed from the usual pattern. For the generally lower gain demand of the amp, except for the phase inverter tube (12AT7A) in the preamp, the 12AX7A is used, which is designed to be less "hot" than the mass phenomenon 12AX7. In the output stage 4 pieces EL34 of the company Mullard are used, which enjoys a very good reputation straight in the boutique range.

Fortunately, the Sound City Master One Hundred is a master volume amp, where you can reduce the final volume while maintaining the same preamp distortion, and yes, the power amp saturation is actually within limits with this amp, as the later practical part will confirm. Interesting with this amp is indeed the combination of different elements, which one has divided for example at Marshall on different types. Sound City, for example, has opted for a combination of the vintage-style 4-input patch panel, which is usually only known from non-Master models. The famous patch cable for mixing the two input sensitivities plus the treble alignment is included.

Otherwise, the classic three-band tone control plus presence control, a blue LED and the standby / power switch pair prevail the classic vintage feeling, which is supported by the general appearance. Stylistically matching tolex, plastic binding and a massive carrying handle, everything as you would expect. Of course, this also applies to the rear panel, where only a somewhat unusual-looking, but very sensible impedance selection risks a second look. For the classic vintage layout, a single 16 Ohm output is offered. For fullstack operation (Mercy Us God ...) each 2 outputs which are switchable between 8 and 4 ohms. So any combination of single or 2 identical cabinets should be possible. Otherwise, there is a line out for daisy chain operation to another amplifier (Grace Us God ...) or the feed to a speaker simulation.

With a weight of 20 kg and the dimensions (HxWxD) 29 cm x 65 cm x 26 cm, the Sound City Master One Hundred is even relatively handy for its performance class, but this does not hide the general feel of an all-tube head.


The Sound City Master One Hundred in practice

Well then, what do we expect from an old-school bolide whose layout and sonic approach has been shifted back almost 5 decades? To say it in advance, you get what you see, that is, the amp sounds exactly as you expect it and at the highest level. But everything in order.

It should be clear to everyone that the Sound City Master One Hundred is not a high-gain amp. If you need a distortion beyond a decent lead in the style of a 2203 or 2204 from Marshall, please switch your favorite overdrive or distortion pedal in front of the amp. The amp works like almost all other colleagues of the guard Alltube Crunch Head quite excellent with additional pedals. So far, so good.

However, what pushes the amp right up into the elite of the Crunch league is the basic sound of the amp. Despite the very good vintage flair, both in the humbucker, as well as in the single coil area, the amp has a very unique sound, where you can recognize the signature of Steven Fryette in every stroke. The slightly throaty sound, always with concise high mids, revives the great hits of the sixties and seventies and effortlessly manages to hit the notch between Marshall on the one hand and Hiwatt on the other.

In addition, the amp hangs almost exemplary on the volume control of the guitar and allows even with the volume turned down wonderfully dynamic clean sounds, which can be seamlessly blended into fat crunch riffs. An amp created for the most classic of all sound approaches, in the form of clean and crunch sounds via volume control and an additional pedal for the lead sounds. Just great.

Yes, the amp is big, heavy, bulky and thanks to American manufacturing with about 2,300 € also quite expensive, but it embodies visually and tonally what has made rock'n'roll great. Lucky the one who still has the balls to play such an amp live!

Conclusion

With the Sound City Master One Hundred, an old trademark has been revived under the aegis of Steven Fryette. With new wine in old bottles, the VHT veteran manages to reanimate a Crunch brand of the upper class and create an alternative worth hearing to the big British names of Crunch.

Anyone who has the opportunity to experience a 100 watt all-tube amp in its entirety should definitely test this amp, if only to briefly experience what rock music once meant and why all guitar heroes are either dead or over 70 years old.

- Sound City Amplifiers: A Legacy of British Sound

Sound City Amplifiers is a renowned British amplifier company known for its high-quality products and iconic sound. The company was founded in the 1960s in England, and it quickly gained a reputation as a manufacturer of premium amplifiers that produced a distinctively British sound. The Sound City brand has been used by many legendary artists, including The Beatles, The Who, and Pink Floyd, among others.

History of Sound City Amplifiers

Sound City Amplifiers was founded in 1967 by sound engineer and designer, Dave Reeves. Reeves had previously worked for Hiwatt Amplifiers, where he gained valuable experience in amplifier design and construction. He started Sound City Amplifiers with the aim of creating an amplifier that could deliver the kind of sound he had always dreamed of.
Reeves was a perfectionist, and he spent a lot of time experimenting with different components and circuit designs to create the perfect amplifier. He eventually settled on a design that featured four EL34 power tubes and a unique preamp circuit that gave the amplifier its distinctively British sound. The result was the Sound City 120, which quickly became a hit with musicians looking for a high-quality amplifier with a unique sound.

Over the years, Sound City Amplifiers continued to produce high-quality amplifiers that were renowned for their power, clarity, and tone. The company's products were used by many legendary artists, including The Beatles, The Who, Pink Floyd, and many others.
However, despite the popularity of its products, Sound City Amplifiers struggled to compete with larger companies such as Marshall and Fender, which had more extensive marketing and distribution networks. The company eventually went bankrupt in the 1980s, and its assets were sold off to other companies.

Legacy of Sound City Amplifiers

Despite the company's bankruptcy, the Sound City brand continued to be associated with high-quality amplifiers and British sound. The Sound City name was used by other companies to produce amplifiers that tried to replicate the original Sound City sound. However, many musicians believe that nothing can match the sound of the original Sound City amplifiers produced by Dave Reeves in the 1960s and 1970s.

Today, vintage Sound City amplifiers are highly sought after by musicians and collectors who appreciate their unique sound and historical significance. They are often used by musicians looking to recreate the sounds of the British rock bands of the 1960s and 1970s.
In recent years, the Sound City brand has been revived by a company called Sound City Amplification. This new company is dedicated to producing high-quality amplifiers that stay true to the original Sound City sound. The company produces a range of amplifiers, including the SC30 and SC40, which are designed to replicate the sound and feel of the original Sound City 120.

Conclusion

Sound City Amplifiers is a company that has had a significant impact on the music industry. The company's high-quality amplifiers and unique sound have influenced generations of musicians and continue to be appreciated today. While the original company may no longer exist, the Sound City name lives on through vintage amplifiers and a new generation of products that seek to capture the essence of the original Sound City sound.


- All About Tube Amplifiers:

The Warm and Vintage Sound of Full-Valve Amplifiers
Tube amplifiers, also known as valve amplifiers or "tube amps," have been a staple in the world of music since the early 20th century. These amplifiers are known for their warm and vintage sound, and they are popular with musicians and audiophiles alike. In this article, we'll take a closer look at tube amplifiers, including their history, how they work, and why they are still popular today.
History of Tube Amplifiers.

Tube amplifiers were first developed in the early 20th century, and they quickly became popular in radio broadcasting and public address systems. They were also used in early guitar amplifiers, and they played a key role in the development of electric guitar music in the 1940s and 1950s.
In the 1960s, tube amplifiers reached their peak of popularity, as they were used by many iconic guitarists, including Jimi Hendrix, Eric Clapton, and Jimmy Page. However, in the 1970s, solid-state amplifiers became more popular due to their smaller size, lower cost, and higher power output. As a result, tube amplifiers fell out of favor for a time.

In recent years, however, tube amplifiers have experienced a resurgence in popularity, as musicians and audiophiles have rediscovered their warm and vintage sound. Today, tube amplifiers are used in a wide range of music genres, including rock, blues, jazz, and more.
How Tube Amplifiers Work.

At their core, tube amplifiers are relatively simple devices. They consist of a power supply, a preamp, and a power amplifier. The power supply provides the high voltage needed to power the tubes, while the preamp amplifies the incoming signal from the instrument or audio source. The power amplifier then amplifies the signal further, and sends it to the speakers.
The key to the warm and vintage sound of tube amplifiers is the use of vacuum tubes, also known as valves. These tubes are made of glass or metal, and they contain electrodes that are heated by a filament. When the filament heats up, it causes the electrons inside the tube to move around, which creates an electrical signal. This signal is then amplified by the tubes, which add a unique character to the sound that is often described as warm, rich, and organic.

Advantages and Disadvantages of Tube Amplifiers

One of the main advantages of tube amplifiers is their warm and vintage sound, which is difficult to replicate with solid-state amplifiers. Tube amplifiers are also known for their smooth distortion, which is highly valued by guitarists who want to add a gritty edge to their sound.
However, tube amplifiers also have some disadvantages. They are generally more expensive than solid-state amplifiers, and they require more maintenance. The tubes need to be replaced periodically, and the amplifiers themselves can be quite heavy and bulky. They also tend to be less efficient than solid-state amplifiers, which means they may not be suitable for high-volume gigs.

Conclusion

In summary, tube amplifiers are an important part of the history of music and audio technology. They are known for their warm and vintage sound, and they are popular with musicians and audiophiles who value the unique character of tube amplifiers. While they may be more expensive and require more maintenance than solid-state amplifiers, the warm and organic sound of tube amplifiers makes them a popular choice for many music lovers.

TEST: Two Notes Revolt Guitar Preamp

The desire to push one's personal sound more and more in the direction of miniaturization and thus to realize a sound as grown-up as possible with minimal means is the big topic of the last years. Even if the official all-tube heads still represent the measure of all things in terms of dynamics and compression, only a few musicians are still willing to take on the extra effort in transportability and only a few artists are able to pay a corresponding crew for such work with their live earnings. The French manufacturer Two Notes, known from the field of loudspeaker emulation, is therefore also preparing to launch a comparatively puristic preamp solution in the form of the Two Notes ReVolt Guitar Preamp, so that a maximum of high-quality sounds can be achieved with small dimensions. 

The concept of the Two Notes ReVolt Guitar Preamp 

The Two Notes ReVolt Guitar Preamp is an analog, three-channel preamp, which has 6 different sounds due to an additional boost circuit, which is activated by pressing the respective channel switch twice. Each of the three channels has its own gain / volume section, with the Clean channel having a two-band tone control, while the Crunch and Lead channels share a common three-band tone control. As always, Two Notes is not allowed to name the models of the three channels for trademark reasons, but judging by the pictograms we have once again the popular combination of Fender for Clean, Plexi for Crunch and Soldano for High Gain at the start. The preamp can be used in live as well as in home studio mode, since you can also go directly into the DAW via a balanced XLR out along with switchable speaker simulation. Sonically, the Two Notes ReVolt Guitar Preamp gets its gain from a 12AX7 tube, which is driven to 200 volts. For better signal management, the Two Notes ReVolt Guitar Preamp has MIDI In / Out, which, however, due to space constraints, have only been implemented in mini-jack. unfortunately, the product only comes with a corresponding adapter, i.e. for a fully comprehensive management, it requires the purchase of an additional adapter. 

To operate the Two Notes ReVolt Guitar Preamp, an external 12V / 600 mA is required, which is included with the preamp. The preamp, manufactured in China, was placed in a very sturdy case, which is a mix of plastic and aluminum. The built-in preamp tube was placed under a transparent plastic window and is thus well protected from external influences. The activation of the boost circuit is visually signaled by an additional activation of a red light inside the tube window. The preamp stands on four soft rubber feet, which even on a glass plate still provide good protection against accidental slipping. To make the Two Notes ReVolt Guitar Preamp audible, there are no less than five different methods, each of which is a useful application in its own right. 

1) Direct Recording to DAW: Using the built-in speaker simulation, you can play directly into the DAW via an appropriate interface. You can also deactivate the simulation via a mini-switch on the front of the cabinet if you prefer a different simulation. 

2) Live via a DI box: The XLR output plus the speaker simulation is also used for this. However, you can only hear yourself via appropriate monitoring using wedges or in-ear systems. A switchable ground lift eliminates any ground loops. 

3) As a preamp before or in the FX loop of the amp: You can switch the Two Notes ReVolt Guitar Preamp either before the clean channel of the amp or for greater neutrality in the return of the FX loop. Here, however, it is essential to make sure that the output level of the preamp and the input sensitivity of the amp match. The preamp also has an internal FX loop to place modulation or room effects at the right loop-in point. 

4) As a headphone amplifier: You can practice silently via a mini-jack output on the front of the case. Conveniently, there is an AUX In, also in mini jack for feeding the playback directly next to it. 

5) Using the 4 Cable method: A detailed description of this method follows this paragraph. 

What is the 4 Cable Wiring? The 4 Cable Wiring is an extended wiring method, if you have a full preamp and an amp each with a serial FX loop available. In contrast to the "simple" wiring of a preamp, the switching before the preamp of the amp or the pure use of the output stage of the amp, with the 4 Cable Wiring method you can use one or more sounds set at the amp in addition to the 6 sounds of the Two Notes ReVolt Guitar Preamp. Especially when used in a MIDI context, as long as the amp and possibly external effects also have a MIDI interface, the sun rises here in terms of sound variety. To make the most of the system, the Two Notes ReVolt Guitar Preamp has a separate activation of the circuit, also to be operated via a mini-switch on the front of the housing. 

 To implement the 4 Cable Wiring, connect the instrument cable (or an appropriate transmitter) to the external preamp, then go via Out of the preamp to the return of the amp, further from the send of the amp to the return of the preamp and finally from the send of the preamp to the input of the amp. If you now deactivate the preamp and switch it to bypass, the amp can be played normally, but if you activate the preamp, only the amp's output stage is used. Provided you get the input and output levels perfectly balanced, you can add several channels of preamp to your amp at once. In other words, the preamp of the amp itself behaves like an FX pedal that you can turn on and off at will. 

The Two Notes ReVolt Guitar Preamp in practice 

To start with, I intentionally recorded all sound files with the internal speaker simulation only, as I believe this signal flow will be the primary application of the Two Notes ReVolt Guitar Preamp. While some users will certainly use a separate speaker simulator to improve the overall sound, just as some friends of the 4 cable method will be happy to have 6 additional channels, in the general "smaller, lighter, simpler" trend the pedal will definitely find its main application in the stand alone variant. First of all, it is noticeable that the preamp produces very little ambient noise, which can also be well controlled with the volume control of the guitar during breaks in the game. This is an even more important point, since the Two Notes ReVolt Guitar Preamp does not have a noise gate. Clean, the preamp convinces all along the line. The tuning is tasteful, the attempt to emulate a Fender clean channel succeeds over long distances. With increasing distortion, however, the Two Notes ReVolt Guitar Preamp's speaker simulation unfortunately also reveals the problem of the signal's lack of dynamics and the sometimes "dull" treble reproduction due to the lack of resolution. Like almost all speaker simulations that I have come across so far, this one is unfortunately only a simulation of what a regular miked speaker is capable of. There will certainly be many users who will use the argument of "doesn't stand out in the overall sound anyway" against the very good workmanship and the successful transportability, but in the A/B comparison, the microphone clearly comes out on top. The whole thing is confirmed, by the way, if you connect the Two Notes ReVolt Guitar Preamp to a high-quality all-tube head using the 4 cable method. In this case, the signal sounds much tastier, better in dynamics, and generally much higher quality. My personal recommendation would therefore be to use a very good single channel head, for example a 2203 or 2204 Marshall, whose basic sound you definitely want to use, and then blow it up to a seven channel using the Two Notes ReVolt Guitar Preamp. Warning, don't forget, some vintage marshalls don't have an FX loop! 

Conclusion 

With the Two Notes ReVolt Guitar Preamp, the French company has a very flexible tool in its portfolio, whose field of application is widely spread and very flexible. Even though the built-in speaker simulation doesn't quite convince me, the preamp in 4 cable wiring delivers a convincing performance, which especially turns a single channel into a multi-channel multifunctional tool. Highly recommended!

These pedals are designed to provide guitarists with a versatile range of tonal options, allowing them to shape their sound to fit the specific needs of any musical situation. Preamp pedals are especially popular among players who prefer to use a clean or slightly overdriven tone, as they allow for greater control and flexibility over the sound of their guitar. One popular type of preamp pedal is the preamp floor effect pedal, which is designed to be used in conjunction with other effects pedals, such as overdrive, distortion, and modulation pedals. These pedals typically offer a range of tone-shaping options, such as EQ controls, gain settings, and various voicing options. They may also feature built-in effects like delay and reverb. One of the advantages of using a preamp floor effect pedal is that it allows guitarists to shape the tone of their guitar before it enters the signal chain of other effects pedals. This can be especially useful for players who use a lot of distortion or other high-gain effects, as it can help to prevent their tone from becoming muddy or overly saturated. Preamp floor effect pedals are also useful for players who need to switch between different guitar tones quickly and easily, as they allow for instant changes to the tone of the guitar without the need to adjust amp settings or swap out different pedals. This can be especially useful for live performance situations, where the ability to switch between different tones quickly and easily can be the difference between a great performance and a mediocre one. Overall, preamp floor effect pedals are an essential tool for guitarists who value versatility and control over their tone. They offer a range of tonal options that can be tailored to fit the specific needs of any musical situation, and are an essential part of any serious guitarist's rig. 

- Preamp tubes, also known as preamp valves, are a type of vacuum tube used in guitar and bass amplifiers to amplify the guitar signal before it is sent to the power amp section of the amplifier. These tubes are an essential part of the amplifier's signal chain, as they are responsible for shaping the overall tone and character of the sound. Preamp tubes are typically found in the preamp section of the amplifier, which is where the guitar signal is first amplified and processed before being sent to the power amp section. These tubes are responsible for amplifying the signal to a level that is suitable for the power amp section, and they also shape the overall tone of the guitar by adding warmth, harmonics, and distortion. There are several different types of preamp tubes available, each with its own unique characteristics and tonal qualities. Some of the most common types of preamp tubes include the 12AX7, 12AU7, and 12AT7 tubes. The 12AX7 tube is one of the most popular preamp tubes, known for its high gain and ability to add warmth and distortion to the guitar signal. The 12AU7 tube, on the other hand, is known for its lower gain and cleaner tone, making it a popular choice for jazz and clean playing styles. One of the advantages of using preamp tubes in a guitar amplifier is their ability to add warmth and natural harmonics to the guitar sound. Unlike solid-state preamp circuits, which can sound sterile and lifeless, preamp tubes have a natural compression and saturation that adds depth and complexity to the guitar sound. However, preamp tubes do require regular maintenance and replacement, as they are subject to wear and tear over time. It is important to regularly check and replace preamp tubes when necessary to ensure the amplifier is operating at peak performance and producing the best possible sound. Overall, preamp tubes are an essential part of any guitar or bass amplifier, and are responsible for shaping the overall tone and character of the sound. They offer a natural warmth and complexity that cannot be achieved with solid-state circuits, and are an essential component for guitarists looking to achieve a professional-quality sound.

TEST: B.C.Rich Rich B Legacy Double Neck

The occasions when a broad smile spreads across my face while unpacking an instrument have become rare. The majority of all test instruments offer very good quality at sometimes extremely low prices, but sometimes disregard the famous show aspect, the "Punch and Judy", which makes the guitar sector so entertaining. All the nicer, when an instrument like the BC Rich B Legacy Double Neck with its 6-string / 12-string construction, which belongs to a proper "Punch and Judy show", almost immediately puts all the attributes on the tester's bread ;-) 

The construction of the BC Rich B Legacy Double Neck 

Few guitar manufacturers are as focused on the hard'n'heavy sector as B.C.Rich, founded by Bernardo Chavez Rico in 1969. Strictly speaking, the term "hard" can be left out of the stylistic repertoire, since the sometimes extremely unusual guitar shapes can be found almost exclusively in metal. Even if the resonance behavior of the manufacturer's higher-quality guitar lines in particular could certainly cover the entire spectrum of guitar music tonally, using a genuine BC Rich shape outside of bludgeoning, shredding and thrashing would, gallantly put, draw the undivided attention of colleagues and the audience. 

Aside from the moderate body shape by BC Rich standards, the overall appearance of the instrument can simply be described as monstrous. Placing the instrument in a regular guitar stand? Completely impossible, which is why it also comes with a high-quality case to hand! It's obvious that a doubleneck in itself blows up the regular appearance, but what BC Rich adds in terms of circuitry extravaganzas finds its origin in the sound aesthetics of the eighties. In his time it was quite common to get out pretty much everything in terms of tonal variations, which offered passive pickups of his time and in the present instrument to a collection of a total of 13! Knobs, switches and mini switches. More on that later. 

Even though the BC Rich Rich B Legacy Double Neck is available in two different finishes (Trans Red / White), the present transparent Cherry finish will probably create the strongest association with the forefather of all Doublenecks, the Gibson SG Doubleneck, which was the Jimmy Page showcase model for the live versions of "Stairway To Heaven". To be fair, it should also be mentioned that Don Felder also used a white version for the live performances of "Hotel California", probably an equal competitor in terms of hit potential. 

In terms of design, however, the instruments are worlds apart, starting with the neck construction. Although also made of mahogany, the BC Rich has the more vibrationally favorable neck-through variant on both necks, whereby the necks are not parallel, but at an acute angle towards the body. An extravagant, albeit very sensible solution was implemented for the 12-string neck in terms of tuning machines. What may seem like an optical gimmick at first glance, in reality has a solid reason. We are talking about the placement of the octave tuners behind the one-piece bridge construction used on the necks and the associated 6 drill holes in the headstock of the neck. 

On the one hand, the strings can be tuned much more relaxed, since the tuners do not sit so close to the headstock together. On the other hand, however, the BC Rich Rich B Legacy Double Neck is spared the head heaviness of the Gibson model, which constantly presses down in the musician's hand due to the 18 tuners and the huge headstock on the 12-string neck. A very successful detail. 

The hardware 

In the hardware area, light and shadow alternate. Extra praise goes to the built-in Super Rotomatic tuners from Grover, which on the one hand glide very smoothly over the synthetic bone saddle and with their "rod optics" also make a good visual impression. Also the BCR Quad bridge is in principle a showpiece in terms of mass and mechanics, if, yes, if there were not this buzzing on one of the high E-string of the 12-string neck. 

What happened? Well, after some searching, I was able to find the problem in the contact pressure of the string on the rider. The angle from the rider to the suspension of the ball end on the bridge is so shallow that the resulting contact pressure does not push the string into the notch enough, causing it to strike and buzz in the notch. Although the B-string next to it has the same angle, even the minimally larger string diameter is enough to prevent buzzing. So it is really a matter of fractions of a millimeter. 

You could prevent the buzz by raising the rider a bit, but that would be at the expense of string action, or you could attach a tiny piece of wood/metal to the top of the ball-end hole to make the string drop back at a slightly steeper angle. All in all, a fixable problem, but honestly, a 2 millimeter lower bore would prevent the problem from occurring in the first place. 

The circuit options of the BC Rich B Legacy Double Neck 

To put it in a nutshell, more tonal variety is hard to come by! Whether the extremely diverse sound yield can hold its own in practice is another matter, but the circuitry effort is impressive in any case. Let's start with the three large three-way switches of classic design. Besides the typical pickup circuit neck-both-bridge (2x), the third switch allows neck selection. There actually seems to be no proper 2-way switch for this range, because the built-in 3-way switch is, as with all other Doublenecks of this type with its circuit "both necks" completely counterproductive, because the forced swinging open second neck one tonally shatters the complete performance. Therefore always completely up or completely down with the switch. We continue with six knobs, three of which (Volume, Tone, Tone) are assigned to the six-string neck and three knobs (Volume, Tone, Tone) to the twelve-string neck. It really gets going with 3 mini switches that let the Seymour Duncan-designed HB-103 pickups rotate in phase as well as provide single-coil tone via coil tapping. To top it off, there's a 5-way filter circuit via rotary control, similar to what was used on the top models of Gibson's early ES series. I recommend every guitarist to come to band rehearsal an hour earlier than their colleagues and familiarize themselves with all the possibilities, or else you run the risk of being exposed to qualified comments in the style of "everything sounds the same anyway". P.S. The whole sound variety can only be worked out in clean or very, very marginal crunch. If you use high gain here, you can forget about almost all switches. 

In practice 

Those who are familiar with Doublenecks will know the effect at first contact. In direct comparison to my personal Doublenecks, the BC Rich Rich B Legacy Double Neck is still moderately in the middle in terms of weight, but this does not hide the fact that you are in fact strapping on two guitars at once. If you want to familiarize yourself with the situation, feel free to strap on two regular guitars at once and then try out your favorite moves on stage. The second challenge lies in the clean stringing of the octave strings of the upper neck, especially the accurate cutting of the same. If, for example, the cut ends of the E and A strings are still slightly protruding, you can easily get your right forearm latently perforated or scratched during the performance on the upper neck, something only for the true masochists among you. Before use, you now have the great pleasure of bringing 18 strings into the right tuning ratio. Especially on the 12-string neck, this can degenerate into a time-consuming action, since you can't avoid a certain degree of octave impurity due to the common tabs for each pair of strings. A good "well-tempered tuning" is called for. Now, if you tune the guitar as perfectly as possible, this shimmering sound does have its appeal, but mercy on you if even one string gets out of line. First we come to the dry dock, i.e. playing without a connected amplifier. Those who have been skeptical up to now will now be taught better. All of a sudden there it is, a sustain that is second to none. Of course, with the neck construction used, an excellent vibration behavior was expected from me, but what the oversized body throws again with its mass into the scale, is breathtaking. The vibration behavior of the instrument is overwhelming and compensates for everything that was initially slapped in front of you in terms of haptics. Almost endless tones without any deadnotes and that with a wooden construction, really impressive. Sound-wise, the BC Rich B Legacy Double Neck offers everything you would expect from a guitar of this series. The resonance is excellent, the pickups adequate, the playability good. A clear candidate for a "Very Good" rating, were it not for the faulty E-string suspension on the 12-string bridge, which for me means a point deduction. 

Conclusion 

With the BC Rich Rich B Legacy Double Neck, the American masters of optical provocation have struck properly. The classic 6/12 neck combination allows for an extremely wide range of sounds and offers far more than just the possibility of performing "Stairway To Heaven" and "Hotel California" live. If you need the combination of a shimmering clean 12-string and a classic 6-string rock'n'roll guitar within a song, or just want to really pull off the leather visually for once, you should definitely check this guitar out. P.S. Don't forget your gym subscription ;-)

B.C. Rich Guitars: A Comprehensive Guide 

B.C. Rich is a guitar brand that has been around for more than five decades. The company was founded by Bernardo Chavez Rico in 1969 in Los Angeles, California. B.C. Rich guitars are known for their unique designs, high-quality craftsmanship, and their association with heavy metal music. 

History 

B.C. Rich started out as a custom guitar shop that specialized in creating unique and high-quality instruments. The founder, Bernardo Chavez Rico, had a passion for building guitars and his creations quickly gained a following among local musicians. As the demand for his guitars grew, B.C. Rich began to expand its operations and started producing guitars on a larger scale. The first B.C. Rich guitar was the Seagull, which was released in 1972. The Seagull was an innovative design that featured a distinctive body shape, known as the "Bich" shape, which quickly became synonymous with the B.C. Rich brand. Throughout the 1970s, B.C. Rich continued to release new models, including the Mockingbird, Eagle, and Warlock. These guitars were not only unique in their design, but also featured high-quality components and construction. They quickly became popular among heavy metal musicians, who appreciated their aggressive sound and striking appearance. In the 1980s, B.C. Rich guitars continued to gain popularity, and the brand became even more closely associated with heavy metal music. Musicians like Kerry King of Slayer, Slash of Guns N' Roses, and Chuck Schuldiner of Death all played B.C. Rich guitars, which helped to cement the brand's reputation as a favorite of metal musicians. In the 1990s, B.C. Rich experienced some financial difficulties and went through a series of ownership changes. However, the brand continued to produce high-quality guitars, and by the early 2000s, it had regained its reputation as a leader in the heavy metal guitar market. 

Design and Construction 

One of the most distinctive features of B.C. Rich guitars is their unique and often radical body shapes. These designs are not just for show, however; they are intended to improve the guitar's playability and sound. For example, the Bich shape was originally designed to make the guitar more comfortable to play while sitting down. The Warlock shape was designed to improve the guitar's balance and make it easier to play while standing up. And the Mockingbird shape was designed to give the guitar a fuller, more resonant sound. In addition to their innovative body shapes, B.C. Rich guitars are also known for their high-quality construction. The company uses only the best materials, including mahogany, maple, and ebony, and all guitars are built by skilled craftsmen who pay close attention to every detail. B.C. Rich guitars also feature high-quality hardware, including locking tuners, Floyd Rose tremolos, and DiMarzio pickups. These components help to ensure that the guitars stay in tune, have excellent sustain, and deliver a powerful, aggressive tone.

TEST: Adam Sub10 Mk2

I don't have exact figures, but I'm quite sure that the subwoofer / satellite constellation is the predominant composition in budget studios, probably even in professional studios. The arguments of the proponents of direct radiating systems and the woofer friends are endless and will probably never really be decided. But they probably don't have to be, since everyone has their own opinion regarding space, weight, price, control room dimensions and dispersion below 300 Hz. For the subwoofer advocates, the Berlin company Adam Audio has a professional subwoofer called Adam Sub10 Mk2 on offer, which contrary to expectations is not made in China, but in Germany. I presume to award a plus point for this fact alone in the run-up to the test due to the current economic and political situation. 

 The concept of the Adam Sub10 Mk2 

To introduce the Berlin company Adam Audio would mean carrying owls to Athens. The company has already been working in the high-end area of loudspeaker manufacturing for 23 years and is mentioned in the same breath as the other big names in the industry, especially due to the development of their X-ART tweeter, which is based on the principle of air motion tweeter technology. Today's test, however, will focus on the diametrically aligned frequency range, the bass frequencies. These are always a challenge due to the significantly increased demands in terms of performance and dispersion / directional behavior, especially when it comes to smaller control rooms. To say it up front, if you have a typical home recording control room of 10 - 15 sqm, you can skip this test with a clear conscience, as the performance data of the Adam Sub10 Mk2 is designed for larger rooms. In order to be able to seriously evaluate the waveforms in the bass range, you need at least a medium sized control room in terms of dimensions, and in terms of square meters, you are welcome to go up. 

 Although the power of 200 watts RMS is still within the "normal" range for a home recording studio, the dimensions of (W x H x D): 300 mm x 550 mm x 400 mm and the weight of 21 kg clearly indicate the targeted clientele, which is concluded in a retail price of 1,149, - €. The workmanship of the Adam Sub10 Mk2 is outstanding, even when looking very closely at the details in terms of paint or fitting accuracy, not even the smallest impurity can be detected. 

The first impression of the Adam Sub10 Mk2 

When you look at the Adam Sub10 Mk2 for the first time after unpacking, you'll notice two things that set it apart from the competition. First of all, there is the 10 inch speaker, which stands out with a very large dome and an expansive and voluminous surround. In addition, the diaphragm is very tightly suspended, which is guaranteed to be reflected in the impulse behavior. The second unusual point are the very high feet of the system, which after all have a height of 6 cm. However, another look at the bottom explains this unusual elevation of the cabinet. The bass reflex port is indeed located at the bottom of the enclosure and, as expected, requires a minimum of air circulation to intervene meaningfully in the frequency spectrum. In terms of appearance, the reflex port offers a comparison to a trumpet, especially since the reflex tube extends very deep into the cabinet. The scope of delivery also includes four stick-on, softer felt gliders, which give the comparatively hard designed feet a softer touch and provide protection on harder floors. Furthermore, the Adam Sub10 Mk2 comes with a power cord upon delivery. The front of the Adam Sub10 Mk2 contains two LEDs, which inform about the operating status (On / Standby). Should the woofer ever become overloaded, the lower standby LED will flash red. 

The back of the Adam Sub10 Mk2 

All the control and switching functions of the Adam Sub10 Mk2 have been placed on the back of the cabinet. Interestingly, despite the professional orientation of the product, the budget department was not disregarded. In addition to the two left / right inputs and the two satellite outs, both of which are designed as standard in XLR lockable, both connections are also available in RCA, perhaps to be able to sound the local party cellar if necessary. Via an electronically buffered Sub Out, which receives the input signal unchanged, several woofers can be connected in series in the daisy chain principle to provide adequate sound even in larger rooms. Two additional rotary controls calibrate the volume of the Adam Sub10 Mk2 and the crossover frequency to the satellites. The volume control passes the signal at 0 dB 1:1 to the power amplifier and allows a regulation from -60 dB to +6 dB. The crossover frequency is continuously adjustable from 50 - 150 Hz, while the woofer response is specified at 25 - 150 Hz. 

Three additional push switches allow further adjustments: 

- Mode: this switch sets whether the woofer turns off after 15 minutes without an applied signal, or whether it stays on all the time. Due to power saving, the signal - on mode is recommended. 

- Satellite Filter: Here you can set whether the satellites are operated flat without bass limiting, or whether a high-pass filter is set at 85 Hz. My personal experience speaks in favor of setting a high-pass filter, since the satellites work much more relaxed in this case due to the lower bass load. 

- Subwoofer Phase: Probably the most important switch on any subwoofer. It is well known that the calibration of the subwoofer and its positioning is decisive for the sound and must be carried out meticulously in any case. Exact instructions can be found on the web in abundance, so I will spare myself a further explanation of what is to be considered in the positioning of a woofer. Said switch enables the 180 degree phase rotation, with which one can already effect quite a bit with the correct positioning. As you can see, the Adam Sub10 Mk2 is very clearly structured, which makes it much more difficult to operate it incorrectly. Regarding the crossover frequencies and the positioning of the woofer in the room, I recommend not only to consult the commercially available hardware or software solutions, but also to find the optimal point for the placement of the woofer with very simple solutions like walking around the room. Only from the notorious placement in the corner (each wall increases the sound pressure of the woofer by about 6 dB, that is, a placement in the corner increases the sound pressure by 18 dB) I can only advise against. Even if the first listening impression sometimes seems very voluminous, the precision of the sound usually suffers immensely. 

In practice 

According to Adam Audio, the Adam Sub10 Mk2 needs a few days of operation to settle in. So if the system sounds a bit "brittle" or "stiff" during initial operation, this is normal. Especially woofers have to be built extremely torsionally stiff in order to be able to counteract the occurring forces, which can lead to a latent "hard" sound at the beginning, but this will disappear with time. Already at the first notes the class of the Adam Sub10 Mk2 becomes apparent. Before I even started setting up the woofer, the system convinces with an incredibly finely defined basic sound, which should not change until the end of the test operation. The system sounds very voluminous and yet tight, so that even the low bass range below 50 Hz is still reproduced very cleanly and accentuated. This definition is maintained even at high volumes, so you wouldn't want to change much at first. Adam Audio, however, goes one better, as long as you have found the optimal transfer point to the satellites, especially with the help of the high-pass filter. However, you should also perfectly match the setup of the satellites here, otherwise phase problems can occur. But once this area has been clarified, the Adam Sub10 Mk2 really convinces in all points. Even with a very critical approach, I couldn't find a weak point in the system, which ultimately has to lead to the highest score. A really recorded studio subwoofer! 

Conclusion 

With the Adam Sub10 Mk2, the Berlin manufacturer carries an outstanding studio subwoofer in its portfolio. The system convinces all along the line with a very defined and voluminous sound, very good workmanship and a practical concept that covers all important points of operation. Who is looking for a very good sounding woofer from German manufacturing for medium to large control rooms, should definitely test the Adam Sub10 Mk2 once!

- A subwoofer is a type of loudspeaker that is designed to reproduce low-frequency sounds, typically in the range of 20 to 200 Hz. These sounds are often felt as much as heard, and can add depth and impact to music, movies, and other audio content. The primary way that a subwoofer works is by using a large driver, typically between 8 and 18 inches in diameter, that is specifically designed to move large volumes of air at low frequencies. This driver is mounted in a specialized enclosure, or cabinet, that is designed to optimize the subwoofer's performance by controlling the movement of the air and minimizing distortion. When a subwoofer receives an audio signal, the driver begins to move back and forth in response to the electrical signal. As the driver moves back and forth, it causes the air inside the cabinet to move as well, creating sound waves that radiate out into the room. Because the driver is designed to move a large volume of air, it is able to reproduce the low-frequency sounds that other speakers may not be able to handle, such as deep bass notes in music or rumbling sound effects in movies. One of the key challenges in designing a subwoofer is controlling distortion. Because low-frequency sounds require a lot of energy to produce, it is easy for the driver to become overworked and produce distortion, which can result in a muddy or unclear sound. To combat this, subwoofers often use advanced technologies such as high-quality drivers, specialized enclosures, and advanced signal processing to minimize distortion and produce clean, accurate sound. In addition to providing low-frequency sound, a subwoofer can also help to improve the overall sound quality of an audio system by taking some of the burden off of other speakers. By handling the low-frequency sounds, a subwoofer can allow other speakers in the system to focus on reproducing midrange and high-frequency sounds, which can result in a more balanced and natural sound. Overall, subwoofers are an important component of many audio systems, particularly in settings such as home theaters and music studios where accurate, high-quality sound is essential. By reproducing low-frequency sounds with accuracy and power, subwoofers can help to create a more immersive and engaging audio experience.
