TEST: Solar Guitars Chug

 One thing you have to give Ola Englund, who has converted from an active musician to an influencer, is that it feels like not a month goes by without a new solar product appearing on the market. As managing director of Chug Express SL, which is based in Spain and into which Solar Guitars has been merged, Ola Englund is focusing on consistently expanding his portfolio in addition to his advertising videos, which also seem to be daily, and which have now gone beyond the development of string instruments for the first time. We now have the high gain pedal Solar Guitars Chug for testing, which, according to the advertising message, is supposed to take over the high gain channel of an amp.

The concept of the Solar Guitars Chug

As befits a real influencer, Ola Englund also needs a pithy saying that should become his trademark. "Will it chug?" is a humorous unique selling point with which O. E. tests various guitar / pedal / amp / cabinet / speaker / microphone constellations in his videos for their sound capabilities. In this sense, the naming of the pedal is a logical continuation of its word creation and a very successful marketing move.

The pedal itself makes no secret of its field of application in the manufacturer's attached description. The concept aims to add another high gain channel to an existing amp by using the Solar Guitars Chug in front of the clean channel, or you can use the pedal as a standalone preamp and try to achieve a good sound using a power amp/cabinet or speaker simulation solution.

The pedal uses an extensive 5-band tone control with separate gain feed for the treble or bass and an internally installed noise gate, which is intended to put a stop to the inevitably generated noise.

The construction of the Solar Guitars Chug

The Solar Guitars Chug pedal comes in a solid metal design, with four countersunk Allen screws fixing the upper front plate to the lower metal tray. The pedal only consumes 100 mA of power and should therefore be able to be operated with almost any 9V DC power supply. A power supply is not included and battery operation is not provided. In order to be able to operate the pedal without a pedal board, four adhesive rubber feet are included with the pedal.

The pedal comes with a simple, four-language manual, in which the translation program uses angular and not exactly practical translations to quickly convert the original English text into Spanish, French and German. Perhaps you should have a native speaker from the local music scene take a look at it and translate the already correct text into a musician-compatible version. The external image is good.

To compensate for the cable extensions that occur, the Solar Guitars Chug Pedal has a buffered bypass, which in my opinion turns out to be the more sensible decision, especially in the high gain range. The "holy grail" of true bypass may make sense in the blues area due to the treble attenuation from a total cable length of 6 meters and more, but normally the guitarist wants to lose as little treble as possible in bypass mode. If you want to do without a downstream buffer pedal, you have the option of doing so with a buffered bypass. Be careful, always pay attention to the order in which the pedals are on the board.

There are a total of 6 double-axis potentiometers on the Solar Guitars Chug Pedal for controlling all parameters, although with two control ranges (middle and gain) the two axes have been combined into one controller. The user can choose between five frequency ranges (depth, bass, middle, treble, presence) in the upper row, while the lower range takes over the output volume, the threshold of the noise gate, the gain level and the two level controls for the low and high frequency ranges.
A red/green combination LED also visually indicates whether the noise gate is blocking the incoming signal (red) or letting it pass (green), depending on the threshold setting. Unfortunately, the green LED in particular has the problem that you can no longer tell whether the pedal has been switched on or not when the light is a little stronger. This can cause problems, especially at open air events in daylight.

In my opinion, installing a noise gate within a high gain distortion pedal is a very sensible feature, as you cannot avoid buying a separate noise gate pedal if you do not want to deactivate the distortion pedal immediately when you are taking a break from playing. Remember, if turning down the guitar's volume control does not produce the desired effect, a noise gate must be put in the signal path. If you have ever tried to find the optimal threshold when using the guitar's volume control, you will know what I am talking about. However, this is not important for simple on/off metal thumping, as you only run the risk of a fading chord being strangled if the setting is too hard.

The Solar Guitars Chug Pedal in practice

Despite all the flexibility of the extensive sound control, the double potentiometers give cause for criticism in two ways when it comes to practical suitability. Firstly, you can only see the control position "black dots on a black background" if you turn the pedal against the light and get a rough idea from the reflections of the recesses. Readjustments on stage? Only by ear!

The double potentiometers also have the unpleasant property that if you move the inner potentiometer, for example, you turn the outer potentiometer at the same time, without touching it. The same applies the other way round: move the outer potentiometer and adjust the inner potentiometer as well. In plain language, this means that you can only adjust one of the double potentiometers separately by holding the axis of the other potentiometer firmly. A fiddly job beyond compare. Perhaps just a few fastening screws are tightened too tightly, but without visual control and guaranteed double action, managing the parameters is really completely impractical.

It is interesting that the Solar Guitars Chug pedal produces comparatively little background noise even when the gain control is fully turned up. In this sense, the noise gate has significantly less to do than with various competing products. Apart from that, however, it works very tastefully, regulates smoothly and leaves a very good impression.

In terms of sound, you might get the impression that the Solar Guitars Chug pedal has 2 bass and 3 treble controls. The midrange control is set very high in terms of frequency and would perhaps even pass as a treble control on other pedals. The pedal's presence control offers a frequency range where the description "chainsaw" would be a huge understatement. In general, the Solar Guitars Chug pedal is very treble-heavy. In all of the sound files included, the treble and presence controls were between 8 and 9 o'clock, i.e. almost completely turned down. So if you're looking for the classic Scandinavian chainsaw massacre scratching, you've come to the right place.

As a basis for the sound files, I used my best "pedal amp", the Sound City Master 100, which generated a very neutral, slightly distorted sound as the basic setting. The guitar was an LP Standard from 2014, and the cabinet was a Marshall 412 with Celestion G12 75T and two Shure SM57.

The fact that the Solar Guitars Chug pedal is designed exclusively for high gain can be seen from the fact that even with the gain control turned all the way down, we are almost in the lead range in terms of the gain structure. The amp can be boosted very nicely using the out control, but the high distortion spoils the typical booster characteristics a little. But the pedal was not designed for this area either.

In general, the pedal "bites" very strongly in the basic sound, the tendency of which can never be completely removed due to the strong treble characteristics. In return, however, the pedal can be used to give the dullest amp a massive boost of treble. For example, a single-channel amp whose clean sound was deliberately set to be soft and low in treble can be massively inflated with the Solar Guitars Chug pedal and built up into an independent second channel. All in all, the Solar Guitars Chug pedal is a very flexible metal distortion pedal that, in my opinion, still has a few small teething issues, but these can be fixed with relatively little effort in the MKII version.

Conclusion

With the Solar Guitars Chug Pedal, the Spanish manufacturer has a distortion pedal in its portfolio that has been uncompromisingly bred for high gain. The very extensive tone control allows for many adjustment options, especially in the treble range, and enables the setting up of an independent, additional channel on the amplifier.

TEST: Slate Pro Audio Fox

 The Slate Pro Audio Fox is a two-channel microphone preamplifier in which the two channels each have two independent circuits that can be combined if necessary.

The concept of the Slate Pro Audio Fox

There is probably no sound engineer who has not asked himself at least once which microphone preamplifier to choose when equipping his studio. The same thing happened to Steven Slate several times during his work in the recording studio, when colleagues asked him whether they should go for Neve, API or Millenia. His answer was always the same: you should get all the microphone amplifiers available and choose the best one for the respective application.

It was foreseeable that this answer would not be met with great enthusiasm, even for monetary reasons. However, there is also no question that, depending on the application, the British division, which is more warm and saturation-oriented, has clear advantages, or if you prefer a fast, neutral response, you would rather rely on more modern components.

Steven Slade was aware of this when he designed the Slade Pro Audio Fox, a two-channel microphone preamplifier in which each channel can be switched separately between vintage and modern in terms of its sound orientation.

But that's not all - you can also combine the two channels, where you can switch the input and output range between vintage and modern, so that ultimately a wide range of sounds can be created with the input/output orientation vintage-modern or modern-vintage.

Steven Slate points out several times in his reference guide how important the combination of the different sound approaches was to him, because otherwise, according to his own statements, he would have created "just another normal-sounding preamp".

The structure of the Slate Pro Audio Fox

Before we can even say a single word about the structure or function of the Slate Pro Audio Fox, the product, which was developed and manufactured in the USA, draws attention to itself with its weight. At well over 6 kg, this microphone amplifier is by far the heaviest 1U device I have ever come across in my life. Not even 1U power amplifiers can weigh this much. This speaks for the extremely solid workmanship of the product, but also for the rather solid electronics that must be built into the device.

The product is delivered without any rubber feet and is designed exclusively for rack use. Due to the high weight, I strongly recommend either using an additional rack rail at the back or using a suitable substructure to ensure that the weight does not rest exclusively on the front wings. The device also generates a lot of waste heat, so it is important to ensure that a height unit is kept free above the Slate Pro Audio Fox to dissipate the waste heat.

In terms of construction, the Slate Pro Audio Fox has two identical channels, which can be used separately or in the so-called combo circuit. Both channels have a 12-way gain control, which enables a gain of up to 60 dB, and a continuous output control. In terms of inputs, the product has an unbalanced jack input on the front and gold-plated XLR inputs on the back. In terms of outputs, the product has gold-plated XLR and TRS outputs on the back.

6 mini switches give each channel the necessary flexibility, such as a PAD switch that reduces the input signal by 10 dB if necessary, an input switch that uses a green LED to indicate whether the unbalanced jack input on the front or the balanced microphone input on the back is being controlled. We also have a 180° phase change if required and phantom power, which is also indicated by a red LED.

The product's real secret weapon, however, is hidden behind two mini switches, which are grouped together under the CIRCUIT section. These are the COMBO-NORMAL or VINTAGE-MODERN switches. Using these two switches, two completely independent discrete circuits in solid state design can be activated, which are more oriented towards VINTAGE in the style of a 1073 NEVE or towards MODERN in the style of an ULTRA HI-FI SOLID STATE PREAMP. As expected, these extraordinary combination options of the two circuits, which are arranged diametrically opposite in terms of sound, make it possible to achieve combinations that a single product from a single style cannot deliver. This applies in particular to the individual use of the input and output areas of the two circuits.

The front panel is rounded off by the usual power switch on the right, while the back panel has the cold appliance socket, along with a fine-wire fuse accessible from the outside and a voltage selector switch with which you can choose between 110 and 220 volts mains voltage. Perhaps it would be a good idea to upgrade to 230 volts soon. Visually, the manufacturer offers a tasteful matt-gloss contrasting pattern on the front, which is also a unique selling point for the entire product range.

The Slate Pro Audio Fox in practice

The Slate Pro Audio Fox gives a very high-quality feel, not only because of its high weight, but also because of its excellent feel. All rotary controls and switches have a pleasant, stiff switching process, which makes working with the product a real pleasure.

In order to be able to compare the four different "preset" specifications for input and output transformers exactly, I took an untreated vocal recording from the studio and put it through the various settings of the product. I realize that this means that the direct interaction with the microphone is lost, but I chose this in favor of a direct comparison, since four different vocal recordings would each bring with them four different dynamic and tonal effects, which would distort the result.

Let's start with the Vintage preset. In fact, the setting is very tastefully chosen in the direction of Neve and other British colleagues. There is a clear saturation in the entire signal path and the classic mid-range boost is also clearly audible. This setting is very suitable for typical rock vocals, where things can get a bit dirtier and where the extremely fine treble section is not as important as an assertive mid-range.

The Modern setting, on the other hand, is completely different, where the mid-range is handled in a much more neutral and relaxed manner, but the extremely fine treble range from around 5 kHz is very nicely featured. This ensures that the "whispering" sounds come through very nicely and allow for a particularly fine resolution in the high frequency range. This setting is very tasteful in the pop range, where a wide, neutral and very round resolution is required.

Now let's get to the special feature of the Slate Pro Audio Fox, the combination of the two transformer systems with each other. To say it right up front, the two settings convinced me much more than the vintage or modern settings on their own. The combination results in a denser sound in itself, which comes through very well in the mix and which combines the two strengths of the respective systems.

Personally, I would tend towards the Vintage setting in the input and Modern in the output range in the rock range, and for a slightly more popular interpretation the Modern range in the input range and Vintage in the output range. This is of course a very personal perception, which can vary considerably depending on the signal in question and the taste of the producer. The bottom line, however, is that the four preset options of the product generate very subtle differences in direct comparison, but these are nevertheless clearly perceptible and allow for an incredible level of flexibility that would otherwise only be possible with at least two separate outgear products.

Ultimately, this flexibility makes it possible to save on a microphone preamp and, thanks to the stereo design, you can even transmit a stereo signal very nicely, such as the overheads of a drum set, or two corresponding mono signals.

Conclusion

With the Slate Pro Audio Fox, the American manufacturer has a very flexible microphone preamp in its portfolio. With two independent circuits, the product manages to produce both classic British vintage sounds and modern HiFi sounds, with the system's secret weapon being the combination of the two circuits using freely selectable input and output amplifiers.

Due to this design's flexibility, you can save at least one outgear preamp, which is noticeable both in terms of space requirements and finances.

A very good preamp, which has 4 outstanding "presets" of a special kind. Definitely give it a try.

TEST: Sennheiser PSM 300

 We all know the problem of variety when choosing products. Whether it's over 60 different types of jam in the supermarket or choosing instruments/accessories in the music store, the luxury problem of finding the right one for you within the huge selection of products is everywhere. Everywhere? Not at all! For example, if you try to find a wireless link or a wireless in-ear system, you will quickly find that this area is firmly in the hands of just three providers worldwide, plus two OEM providers from the music stores Thomann and Musicstore. In addition to the very successful products from LD Systems, which are in the mid-range price range up to around €450, the high-end league is divided between the German provider Sennheiser and the American provider Shure. The Shure PSM 300 Premium S8 from the latter is available for testing.

Structure and concept

As is well known, in-ear monitoring systems have replaced the wedge area in terms of monitor sound by around 90% and are already considered standard even in the amateur sector. It is therefore all the more surprising that, in contrast to a very large range of earphones, there is only a very limited range of wireless providers, while the selection of wireless transmitters is exploding. So it is not surprising that if you are often on large stages like me, you will actually only find two providers in the respective stage racks in the colleagues' area. Both the electronic and the haptic load on the individual components such as the transmitter and bodypack are very high, so that only the best quality can guarantee a very high and consistent performance.

The Shure PSM 300 Premium S8 presented for testing is priced at €777, in the upper range of the Shure line, but is still around 70% below the price of a comparable Sennheiser product. The product, manufactured in a 9.5 inch half rack unit, is delivered with extensive accessories, such as the transmitter, the bodypack and an external power supply, two rack brackets, a protective cover for the bodypack, a stereo earphone and a BNC antenna extension.

With the PSM 300 series, Shure offers several versions of its radio link, which transmit on different frequencies. The product available for testing works in the LTE mid-gap, which is between 822 - 832 MHz. To minimize the risk of overlap with the upload and download frequencies of commercial providers such as Telekom, Vodafone, etc., the product only transmits in the range of 823 - 832 MHz. The frequency range in question is the last refuge for license-free operation, all other frequency bands are subject to a fee. In addition, operation is permitted throughout the EU except Poland (they want money for operation).

The transmitter of the Shure PSM 300 Premium S8

The transmitter of the Shure PSM 300 Premium S8 is housed in a solid metal housing and is almost self-explanatory in terms of operation, provided you have already dealt with radio links a little. An easy-to-read, monochrome display provides all the necessary audio, RF and system information, such as the input level, group selection, lock status, sync status, whether stereo or mono mode was used and the choice of input sensitivity. In addition to the stereo mode, a MixMode can also be used, in which the personal instrument can be continuously mixed into a master mix. To activate this, all you need to do is hold down the GROUP button on the pocket receiver while the transmitter is switched on. The MixMode indicator light on the receiver display lights up to confirm the setting. The receiver returns to stereo mode after it has been switched off.

On the back, in addition to the regular stereo inputs in TRS, 2 outputs labeled LOOP are particularly noticeable. The LOOP outputs route audio signals to an external device, such as other in-ear monitoring systems, recording devices or stage monitors. The signal at the LOOP outputs is identical to the signal coming from the mixer and is not affected by the transmitter volume or the input sensitivity (line/aux) settings. This makes the LOOP outputs particularly useful when using a mixer that has one or two monitor/aux sends. Otherwise, the rear panel offers the input sensitivity control, which distinguishes between line and aux, and a slider for the mono mix.

The bodypack of the Shure PSM 300 Premium S8

In contrast to some products in a lower price category, the receiver of the Shure PSM 300 Premium S8, called the P3RA, is made of metal, which means it is significantly heavier but also much more stable. According to the manufacturer, the receiver has an operating time of up to 5.5 hours with 2x AA batteries or up to 7 hours with an optional SB900 battery. A three-color LED provides information on the charge level of the batteries (green: 5-7 hours, yellow: 1-3 hours, red (constant): 0.5-1 hour, red (flashing) 0) and thus protects against unwanted surprises.

The range of up to 90 meters stated by the manufacturer also lets you stop, which is sufficient even for the largest music stages in the world and extends from the area of ​​application into the event sector. All information can be accessed quickly and easily via an easy-to-read display in combination with three soft buttons located behind the battery cover. Another very useful feature to save battery life is that the receiver switches to power save mode as soon as no earphones are connected.

The Shure PSM 300 Premium S8 in practice

In general, users attach importance to two things when it comes to a wireless connection: for the "normal" user, the sound, and for the "ambitious" user, the range. With regard to the first point, the Shure PSM 300 Premium S8 can only be given top marks. The 24-bit audio processing enables a dense, yet high-resolution sound that, depending on the quality of the in-ear earphone, reproduces even the finest nuances. In addition, the sound remains stable until the connection is lost and does not change at all even as the distance increases.

With regard to the second point, the whole thing becomes particularly interesting on large open-air stages. In order to get the most out of the respective systems, you can see corresponding "paddles" on almost every large open-air stage, which support the range of both the stage radio and the musician-relevant systems. In order to be able to walk the entire stage area on a small club stage and to perform an occasional show in the audience, 2.4 GHz transmitters or receivers are usually sufficient. For an official 30 - 40 meter stage, however, nothing more can be done for this frequency range.

I made it particularly difficult for the Shure PSM 300 Premium S8 by installing my stage setup in a reduced form in the recording room of my studio (room within a room), closing 2 soundproof doors and then heading out into the open air. Despite the closed room, I was still able to move almost 40 meters away from the building before the signal broke off. An excellent value, which is probably primarily due to the 20 mW transmission power.

However, to reduce the product to just these two points would be to do the system an injustice. The workmanship and design of the P3RA receiver cannot be rated highly enough. The workmanship of the bodypack is put to the test, particularly during an intensive stage show or a hectic instrument change. Here, the metal housing offers real added value compared to the plastic competition. The headphone jack also leaves a very good impression, especially since it is probably subjected to the most stress during operation by "pulling on the cable" and "wildly turning around its own axis".

In addition, the most important information during operation, RCF level and battery status, are easy to see thanks to powerful LEDs on the top of the housing, while other systems usually have this information on the front of the housing. Taken together, the Shure PSM 300 Premium S8 is indeed a top-class product that works at the highest level in all relevant areas. Unreservedly recommended.

Conclusion

With the Shure PSM 300 Premium S8, the American manufacturer has a high-end product in its portfolio. It is not for nothing that Shure is one of the two leading manufacturers worldwide when it comes to radio links and wireless in-ear systems. The system sounds very good, has a very long range and scores particularly well with its very good workmanship and solid design.

If you want to be on the safe side in terms of transmission stability, sound and workmanship, you should definitely take a look at the system.

TEST: Schecter SLS Elite C-7

 The Schecter SLS Elite C-7 is a seven-string guitar that is also equipped with a fanned fretboard and is considered to be part of the Power Strats family.

The construction of the Schecter SLS Elite C-7

Even though Schecter has significantly more models in its portfolio, along with the former big names such as Kramer, Charvel or the still active ESP and Ibanez, Schecter is clearly one of the forefathers of the Power Strats. Since the Stratocaster shape is of course also the biggest revenue generator in Schecter's stable due to its visually simple but ingenious shape, it is not really surprising that the majority of almost every manufacturer, apart from Gibson, is more or less determined to come close to the classic shape.

The fact that the Schecter SLS Elite C-7 we have for testing has very little in common with the original Stratocaster from 1954 is not only clear when you first touch the fingerboard, but is also clearly visible beforehand. Let's just start with the general appearance, which could be described as "pure nature". The instrument is completely varnished transparently, so that the different wood grains shine beautifully through the respective varnish layers. To make the whole thing appear a little more distinguished, the instrument has a very nice, simple, black binding on the upper side of the body as well as in the neck and headstock binding, which gives the instrument a certain sleekness.

In keeping with this, all of the hardware in the form of the tuning machines and the HipShot bridge construction, in addition to the pickups, which come from Fishman, were also kept in black. The tuning machines are locking versions, which, with a corresponding screw on the underside, allow the strings to be firmly fixed and thus increase the tuning stability. The Schecter company logo is printed on the mechanics. However, it is not possible to find out to what extent the mechanics are actually manufactured by Schecter or whether they are OEM products. But it is not really important because the mechanics do a good job due to their manufacturing quality. In terms of the string guide, Schecter has also taken the relatively wide neck into account and the 7 tuning machines with an arrangement of 3 in the bass area and 4 in the treble area with a slightly tapered arrangement ensure that the string guide runs relatively straight from the saddle to the headstock and thus creates as little friction as possible on the saddle notches with regard to the side guide.

Of course, the upper plastic head of the three-way switch and the Speed ​​Dome Master Tone and a Master Volume control are also black. Both controls have the now common push-pull function to be able to switch the Fishman pickups, which are known to have a vintage and a modern orientation, separately. Due to the multiscale design, the pickups are of course installed at an angle in the guitar to ensure even string pickup. However, due to the angled installation, the pickups are unusually wide. I wouldn't be surprised if, despite the seven strings, Fishman used the pickup version of the eight-string guitars to compensate for the "shortening" of the housings by installing them at an angle. A good detailed solution!

Since the pickups are active, a 9 volt battery must be installed inside the instrument. Schecter does this on the Schecter SLS Elite C-7 via the back, where a relatively stiff plastic flap covers the battery compartment. I tried it with my fingernails, but unfortunately the flap could only be opened with a flat-head screwdriver. However, it is generally recommended to take a screwdriver with you so that even if you can open the flap with your fingernails, you can only lever out the 9 volt battery underneath using a screwdriver. Remember, always take some tools with you!

With a nut width of 48 mm, the neck is of course of a different caliber in terms of playability than if you were to take a look at a regular six-string guitar. Even the neck, which is in Ultra-Thin C and, in my opinion, could easily pass as a flat D in terms of its shape, can only rudimentarily convert the feel to "regular". Nevertheless, the instrument must be said to be comparatively easy to play, although the fan fingerboard definitely requires some getting used to.


The wood selection of the Schecter SLS Elite C-7

If you are offered so much wood in its natural color, it makes sense to go into the respective woods in more detail. Firstly, we have the through neck, whose fingerboard has a scale length of 648 mm to 685.8 mm. The different scale lengths are due to the fanned fretboard, which is known to ensure that the different scale lengths give the strings as even a lateral tension as possible compared to a regular guitar.

In order to implement this, a fan-shaped arrangement of the frets must be used, which results in the unusual alignment of the frets. The 24 jumbo frets on the Schecter SLS Elite C-7 have their center at the 11th fret and shift their angle evenly apart according to the scale length towards the headstock and the bridge. Of course, it should not be forgotten that both the saddle and the bridge construction have to follow this alignment, especially since the angle is at its sharpest at these two points.

The neck in question is made of maple, garnished with padouk and walnut strips and has been additionally reinforced with carbon fiber rods. The three colors that are revealed to the eye are a classic light maple, two dark walnut strips, a slightly reddish padouk strip and the aforementioned carbon fiber rods.

Swamp ash was chosen for the attached body wings. This wood is known for its very good vibration behavior and moderate weight, which nevertheless ensures that the instrument, which is significantly more massive in its overall construction than a six-string guitar, still weighs around 3.8 kg, which is roughly equivalent to the upper middle class in terms of weight.

In contrast to the top of the guitar, which has been polished to a high gloss and sealed with a varnish, the back of the instrument, like the neck surface, is only slightly satin-finished with a very thin varnish, so that you can feel the bumps that a natural wood structure brings with it very well with your fingertips.

The Schecter SLS Elite C-7 in practice

What you have already noticed visually and haptically through the features of the instrument is consistently continued acoustically. Due to its construction and features, the instrument is clearly designed for the hard and heavy range, with the progressive element increasing immensely here. The fact that the instrument has been varnished with clear varnish and therefore the high proportion of wood shines through untreated also suggests that the company is much more relaxed in this regard when it comes to the target group. Such a finish would certainly not be met with open arms in black, death, or other white-faced Punch and Judy metal.

One feature is noticeable from the very first note, as soon as you get the first string to vibrate. The magic word is sustain. The entire construction of the instrument is designed to ensure the longevity of the vibration period of the individual notes, and you can hear and notice this. The continuous hold ensures once again that each string and, with it, each note vibrates for an incredibly long time. In conjunction with the Hipshot bridge, which guides the strings through the body, and the completely immobile string construction due to the absence of a vibrato system, the construction ensures that even the highest, thinnest note is still given an excess of vibration period.

The basic sound of the instrument is powerful and yet differentiated, so that even maximum gain structures can be processed well.

Of course, it takes a short period of getting used to it until the brain has adapted its finger movements to the fanned fretboard. This happens surprisingly quickly, however. After just under an hour, my brain had adjusted accordingly and was already able to deal with the different string spacing much better. I am relatively sure that after a few days the system will have become firmly ingrained in the grip technique of every player.

Conclusion

With the Schecter SLS Elite C-7, the manufacturer has a high-quality instrument for the progressive hard'n'heavy range in its portfolio. The workmanship, concept and components are of high quality and offer everything that is needed for this genre.

Among these developments, the 7-string electric guitar stands out as a significant innovation, expanding the instrument's sonic possibilities and catering to the demands of various musical styles. This article delves into the history and evolution of the 7-string electric guitar, exploring its origins, rise to prominence, and the impact it has had on modern music.

## Early Beginnings: The Pre-Electric Era

The concept of a guitar with more than six strings is not new and can be traced back to classical and acoustic guitars. In the 19th century, virtuoso guitarists such as Napoleon Coste and Giulio Regondi experimented with seven-string instruments, primarily to extend the bass range and allow for more complex musical arrangements. These early 7-string guitars, often referred to as Russian guitars, were primarily used in folk and classical music settings.

## The Birth of the Electric 7-String

The advent of electric amplification in the 1930s revolutionized the guitar world, giving rise to the electric guitar as we know it today. However, it wasn't until the mid-20th century that the idea of adding a seventh string to an electric guitar began to take shape. One of the earliest known electric 7-string guitars was custom-built for jazz guitarist George Van Eps in the late 1930s. Van Eps, a pioneer in jazz guitar, sought to expand the harmonic and melodic capabilities of the instrument. His innovative approach to playing and composing necessitated an instrument with a greater range, leading to the creation of his custom 7-string guitar.

Van Eps' contributions to jazz and his use of the 7-string guitar were influential, but the instrument remained a niche item for several decades. It wasn't until the 1980s and 1990s that the 7-string electric guitar began to gain traction in the broader music community.

As the 1990s progressed, the 7-string guitar continued to gain popularity, particularly within the emerging nu-metal genre. Bands like Korn and Limp Bizkit embraced the 7-string guitar, using its extended range to create the down-tuned, heavy riffs that defined the genre. Korn's guitarist, Brian "Head" Welch, and James "Munky" Shaffer were instrumental in bringing the 7-string guitar to mainstream attention, with their debut album "Korn" (1994) featuring prominently downtuned 7-string guitars.

The success of nu-metal bands in the late 1990s and early 2000s further cemented the 7-string guitar's place in modern music. The instrument's ability to produce deep, resonant tones made it ideal for the aggressive, percussive playing style that characterized the genre.

## Technical Advancements and Modern Use

The turn of the millennium saw significant advancements in guitar technology, contributing to the increased popularity and versatility of 7-string guitars. Improvements in pickup design, hardware, and overall construction quality allowed for better sound clarity and playability, making 7-string guitars more appealing to a broader range of musicians.

TEST: Shure GLXD16

 There are now countless guitar and bass transmitters in the 2.4 GHz range. The low-cost range in particular is covered by a large number of products, so that one could believe that the market is sufficiently covered here too. So why does a renowned manufacturer like Shure go ahead and bring a transmitter system like the Shure GLXD16 onto the market in this frequency band for a retail price of €409, which clearly occupies pole position in this frequency segment in terms of retail price? Certainly not without corresponding qualitative ulterior motives! This test shows to what extent this calculation works.

Structure and concept of the Shure GLXD16

First of all, why is a guitar transmitter located in the 2.4 GHz range in the first place? Well, the concept is known to have several advantages and disadvantages. The undisputed biggest advantage is the fact that this frequency can be used worldwide without any license. No restricted use in some countries, no license fees for exclusive use in less used bands. Another advantage is the consistently good sound that can be achieved in this frequency band, although the degree of compression still varies towards a high-quality cable.

The two biggest disadvantages, however, are the constant competition from almost all mobile phones, which are still operating in the most prioritized WLAN 2.4 GHz band and are even latently searching for this frequency in the LTE range, which means that hundreds, even thousands of competitors in the immediate vicinity are fighting with you for the transmission range on this frequency. Disadvantage number 2 is the reduced range, which is known to decrease proportionally with increasing transmission frequency and only comes close to the 10 meter mark for cheap products in the 2.4 GHz range. This is also the reason why other products above this limit have not been able to establish themselves, provided that the legally prescribed maximum transmission power is adhered to. The trick is therefore to make maximum use of the advantages of the frequency, equip the product with additional, useful features and reduce the disadvantages to a minimum.

Like most guitar transmitters, the Shure GLXD16 consists of two units, the transmitter and the receiver, which brings us to the first advantage of the system. The receiver is also a solid floor tuner, whose large, two-digit display in combination with a thirteen-digit LED chain and two arrow LEDs provides information about several functions. Three additional LEDs below the display provide information about the input level, the mute function and the connection to the transmitter. Four additional push buttons can be used to pre-select different groups, edit tunings and select display methods such as arrow display or strobe.

The housing is extremely solid and rests on a rubber mat with two small rubber feet. To protect the displays and push buttons from the soles of your shoes, two raised areas have been attached to the right and left sides of the housing, which also house the system's receiving antenna. A 12 V / 400 mA power supply is included for operation, but the receiver is very flexible in terms of its power supply and processes everything between 9 and 15 volts and a minimum current of 250 mA, which should be found in any better floorboard multi-power supply. The tuner can be switched off if necessary using a small slider and new firmware can be loaded via a USB port on the opposite side of the housing if necessary.

Let's get straight to a point that may not seem so spectacular at first glance, but for me personally is the absolute highlight of the receiver. In normal operation without an activated tuner, the first seven LEDs in the tuner chain show the charge level of the transmitter unit. I don't know how often I have wished for this actually quite simple solution on a floor receiver. The problem is always the same, in the already extremely tense situation on stage, there are sudden interruptions in the signal flow, which can be due to an empty battery, among other things. One look at the charging indicator in combination with the RF field strength LED and there is no point in error. No more tedious tugging on the guitar and strap to bring the necessary information on the transmitter unit into view, simply great!

The transmitter unit

The transmitter of the Shure GLXD16 system is in no way inferior in terms of solid construction. A solid metal housing combined with a very stable retaining clip ensure a lot of confidence in the user and should also survive a fall after accidentally slipping off the strap. Another special feature is the use of a battery, which according to the manufacturer puts everything I have come across in terms of operating time in the shade. With maximum charging, which can take up to 4 hours depending on the charging current used, the system can be operated for up to 11.5 hours under optimal conditions, i.e. 5 shows of 2 hours each should not be a problem.

The transmitter is charged via a USB port either using the power supply unit supplied or a regular mobile phone power supply. A single, three-color LED not only informs about the charging status (green = everything is fine, red on = approx. 1 hour reserve, red flashing = less than 30 minutes), it also informs about any connection searches and any blocking. During charging, this LED also provides information about the charging progress. The only bad thing is the color yellow when it is flashing, as this always indicates a defective battery. As always in this performance class, the transmitter is connected to the instrument with a nearly 80 cm long mini XLR / jack cable, which is an in-house product of high quality. The transmitter antenna used is installed in a cylindrical protrusion for better transmission performance and has approximately the same dimensions as the screw attachment of the mini XLR cable.

The Shure GLXD16 in practice

Before using the Shure GLXD16, you should perhaps consider the special features of the 2.4 GHz transmitters. On the one hand, 2.4 GHz transmitters have a little more difficulty penetrating solid structures such as walls than their MHz competitors, and on the other hand, in open fields and large halls, they have the disadvantage of a slightly shorter range, as there are fewer, or no, reflective surfaces. With these aspects in mind, the Shure system had a much larger buffer in my head in terms of the range of the system than I would expect from MHz systems, for example.

However, as it turned out, my buffer should not be used at all. The system delivered by far the best value that I have been able to achieve with a 2.4 GHz transmitter so far. I could not quite reach the 40 meters mentioned by the manufacturer under optimal conditions, but 30 meters and more were no problem. which is almost the same size as the two large Wacken Open Air stages. As I said, it's all about the spatial dimensions; to what extent the system can withstand the strong stage radio of such stages, I would only have been able to test in the summer of next year in 2022, when I will be playing on the Wacken stage, among other things.

The Shure GLXD16's values ​​were also excellent when it came to penetrating walls. Despite a KS and an additional plasterboard wall, the system still managed almost 20 meters, a value that is well above average. In terms of sound, there was no noticeable difference in frequency to a high-quality cable, in this case Cordial, although the compression level was a little higher than with a cable, which has the advantage of a tighter, denser sound, but at the expense of the dynamic levels. As always in this area, there is no better or worse, just taste.

The guitar cable is really very long at 80 cm and also allows the transmitter to be positioned very high on the guitar strap. If you place the transmitter a little lower, you should wrap the cable around the rear guitar pin 1-2 times, as the same cable is otherwise likely to dangle at knee height.

Conclusion

With the Shure GLXD16, the American manufacturer has what is probably currently the best 2.4 GHz guitar/bass transmitter in its portfolio. Processing, concept, range and detailed solutions such as reading the charge level of the transmitter on the floor unit are in the absolute top league for tuner/guitar transmitter combinations. Anyone looking for a very compact but powerful guitar transmitter for the floorboard should definitely try out the product.

TEST: Seymour Duncan Tweak Fuzz

 Distortion, overdrive, fuzz and all the other subgroups for the most popular effect of all guitarists. Are there seriously any guitarists who don't own at least one "pedal mine" to cut half-waves? Hardly, which is why the selection of products available in the distortion field is almost endless. It is all the more interesting when an established manufacturer of another equipment area targets this segment to take on the top dogs. This is what happened with the company Seymour Duncan, which has primarily gained its fame due to excellent pickups.

Construction:

The Tweak Fuzz is usually mentioned in the same breath as the guitarist Blues Saraceno, especially since his father Alex designed the pedal. The sound approach was to design a pedal that is essentially similar to a vintage fuzz, but is characterized by greater flexibility. While most distortion pedals deliver a more or less fixed sound that can be rudimentarily varied in terms of tone control and distortion level, the Tweak Fuzz has a six-way selector switch to generate multiple presets using various transistors. Ideally, you would actually have six pedals in just one housing.

But hey presto, you'll have no problem finding the device on your pedal board even in the most diffuse stage light - that's what I call a screaming squeaky duck yellow! ;-) First impression after opening the packaging: the device comes in an ultra-stable design, visually flawlessly crafted. Two solid rolled sheets, the base of which is covered with non-slip corrugated rubber, protect the contents of the device against kicks or other rough treatment. Not even your beloved biker boots can cause this construction any problems. Only the three chickenhead-style controls protrude upwards due to the construction and could provide a point of attack if they are treated extremely badly, but who would intentionally treat their floor pedals so badly that they cause the potentiometer spindle to break? In addition to the "tweak switch" mentioned above, the control options are volume and gain. An input and output socket as well as a 9V power supply connection round off a good impression of the workmanship.

After loosening the 4 Phillips screws, the device reveals a neat and tidy interior. 2 circuit boards, short cable runs, a 9V block and a true bypass switch, that's all there is inside the "Fussel Zwickers". To replace the 9V battery, the screws on the base plate have to be loosened; there is no flap to make this work easier. However, since the Tweak Fuzz, like almost all other distortion devices, only requires a small amount of power, in this case 2 mA, this action will occur relatively rarely.

In order to be able to assess the practical suitability of a fuzz, you should first consider the area of ​​application of the device. In contrast to the overdrive, which is often switched on as an additional channel in front of a tube amp, or the distortion, which sometimes gives weak transistor amps a more or less assertive distortion sound, the fuzz occupies a niche that is not quite as mainstream as the above-mentioned protagonists of the "half-wave cappers".

We all know the advantages and disadvantages of a classic fuzz. On the plus side, we have a very characteristic sound, which gives single lines or a vintage distortion in particular the official sound. In addition, fuzz is very popular in the pop sector when it comes to supporting melodic lines on the electric guitar, as it has a high level of assertiveness and is not in danger of drifting into the rock area that pop/dance producers hate so much. On the problem side, many fuzzes suffer from the problem of "mud" coupled with a high "scratch" content in the high frequency range. If you really want to go all out, you should play a fuzz in attack mode without speaker simulation directly into the mixer and listen to it on the studio monitors, it doesn't get more like a razor! This sound is so broken that it's great again.

In order to retain the above advantages and still minimize the disadvantages if necessary, the Tweak Fuzz was equipped with the aforementioned selector switch. It gives the device the ability to sound like a typical fuzz, but also has a few special features up its sleeve, which are listed as follows:

Tweak switch position 1: The sound loses some of its low end, the sound becomes richer in treble and develops somewhat in the direction of a single coil in terms of resonance behavior. The result is a nice, crisp rock sound with a lot of power, suitable almost anywhere where a distorted rock sound in the direction of a "dirty Telecaster" is needed.

Tweak switch position 2: The bass is cut heavily, the midrange is slightly boosted. In this position, the Tweak Fuzz reacts particularly intensively to the guitar's volume control and can be driven almost towards clean when the level is reduced. The guitar sounds sharp, sometimes biting.

Tweak switch position 3: In this position, the Tweak Fuzz slightly touches the distortion terrain without losing its fuzz characteristics. Strong compression and a strong low-mid portion make this sound a kind of "bread and butter" setting. A good basic setting to familiarize yourself with the device.

Tweak switch position 4: Here we touch on typical fuzz terrain for the first time. The sound becomes slightly "mushy" and just manages to avoid the cliff of mud. Single lines are mostly played in this position; the compression is too strong for chord playing and the frequency content is too bass-heavy.

Tweak switch position 5: A variation of position 4, which also makes chord playing possible thanks to a more open sound character. Very thick in the end result and with targeted EQ settings a powerful rhythm sound. Here too, the fuzz sound is retained in a practical way.

Tweak switch position 6: And here is the official fuzz sound with all its typical peculiarities in the style of "take it or leave it". A very brutal low-mid cocktail that polarizes the target group with a strong presence component. You either love this sound or you hate it, black or white, you won't find any shades of grey.

Practice:

I chose a Marshall Head JCM 800 Mod. 2204 (single channel with master) + 4x12" Marshall cabinet with 75 watts Celestion as the basis for the sound sample recordings. The low input was also used to keep the basic distortion moderate. The sound clips were all recorded with a '76 Les Paul Deluxe with EMG 85 PUs, i.e. the basic level is consistently a bit hotter than with passive PUs. However, the Tweak Fuzz also mastered the high output of the active pickups without any problems.

The neutral sound immediately jumps out at you when the FX is turned off, thanks to the True Bypass switch, which can also be operated without the notorious crack when switched on. Another plus point for all settings is the homogeneous interaction of the device with the downstream amplifier. Many pedals give the amplifier a very strong sound of its own during operation or in standby mode, usually accompanied by a narrowed frequency band. Not so with the Tweak Fuzz. The device gives the impression that it is an additional, modified channel of the amplifier. You never have the feeling that there is a foreign body in the signal path; rather, the amplifier experiences an expansion of its sound spectrum.

The range of applications of the Tweak Fuzz can be expanded considerably compared to the classic fuzz, especially via positions 1 - 3. The typical overdrive is not far away here, but never in danger of losing its touch of scratchiness. The spectrum extends from pop rock and blues to modern country, in which the guitar can also hint at a few "balls".

Positions 4 - 6, on the other hand, justify the second part of the product name. With a specific area of ​​application and a basic knowledge of EQ settings, you can coax all the sounds that made the term fuzz famous out of the Tweak Fuzz, be it Hendrix live in a feedback frenzy or Black Sabbath's Tommy Iommi on "Paranoid". It scratches, it rumbles, it mushes and it roars so much that it's a real joy ;-) Nevertheless, the device remains practical without losing the extreme germanium transistor sound and ruining any useful use because of all the muddyness.

Conclusion:
It may be that the Tweak Fuzz opens up a different sound spectrum with other amplifiers, but the single-channel Marshall version in particular is known to harmonize well with upstream distortion pedals. Here you have to try it out, but in this and probably other spartan setups the Tweak Fuzz could or would be completely convincing. Its flexibility makes it stand out from the overly large pool of competitors with similar sounds, with positions 1 - 3 in particular exposing the variability of the device far beyond the box of a classic fuzz. A recommendable device with high practical suitability.
