TEST: AIAIAI Unit-4

 As soon as you start thinking about portable monitoring, all systems currently on the market have the same problem. We are talking about a more or less large layer of cable, which is necessarily attached to the monitor boxes for connecting interfaces, speakers, power supplies or similar. The company AIAIAI has now brought a loudspeaker system onto the market for the first time, which is intended to work in studio quality and does not require any cables. We are talking about the AIAIAI Unit-4, which is developed in Denmark, built in China and I am very excited about the result of the test.

The concept of AIAIAI Unit-4

The basic principle of the AIAIAI Unit-4 can be found in the use of the so-called wireless link technology. The system is delivered with a transmitter, which is connected via USB-C and can either output the signal at 44.1kHz / 16bit via WLAN with a latency of only 16 ms thanks to 2 antennas, or you can use the built-in mini jack socket. Alternatively, you can also output the signal used via Bluetooth, although, as is well known, the same standard cannot be used for professional applications due to the lack of signal security and in particular due to the high latency of 80 ms and more. The range for the transmitter is stated to be 12 meters, which should be more than sufficient for regular studio use.

The first impression

Anyone who is happy about the generally visually attractive packaging range of Apple products will be very pleased with the delivery of the AIAIAI Unit-4. The two boxes come in a very nice box, which is also divided into two individual boxes in which the speakers are packed in a small fabric bag. The boxes can be used horizontally and vertically, although they have small rubber strips on the sides for both horizontal and vertical operation, which are intended to prevent the boxes from slipping. According to the manufacturer, only recycled plastic was used to make the case, which gives you a better feeling about the environmental aspect.

Due to the trapezoidal shape of the housing, the speakers are automatically slightly slanted in the horizontal position, whereby you can choose between using tweeters on the outside or tweeters on the inside. For my part, in such a company the tweeters are always on the outside. Due to the absence of any cables, it is extremely easy to try out different positions of the speakers. Especially when horizontal, you can find out very quickly whether you might want to have the tweeter on the inside. A very big advantage if you work without any cables.

However, you can also purchase additional rubber pads for vertical operation, with which you can change the angle of attack of the speakers to suit human hearing. To protect the loudspeakers, two magnetic loudspeaker grilles are included, which protect the high and low tones from haptic influences from outside, which is particularly noticeable during transport.

The housing of the monitors is made of plastic and the manufacturer explicitly points out that the design of the system is modular and that all components of the system can be accessed by loosening just two screws. This should make the system very easy to repair and individual parts should be very easy to replace. In addition to the boxes and the transmitter, the scope of delivery includes a charging power supply plus the necessary cables and a simple manual.

You can immediately tell that the manufacturer attaches great importance to the visual appearance, which it achieves across the entire range. The low tones are enclosed in an LED light ring, which signals whether the system is activated or switched off during operation as well as in shutdown and turn-on mode. There are three push buttons on the top of the case, one to turn the product on and off and a plus and minus button for the general volume of the product. The brightness of the LED ring can also be adjusted via a mobile app.

The performance data of the AIAIAI Unit-4

As you can tell from the product name, the AIAIAI Unit-4 has a 4" woofer and 1" silk dome tweeter. The Class D amplifier delivers a power of 2x 30 watts in continuous power and 2x 80 watts peak. If necessary, you can also control the speakers traditionally via TRS cable or mini jack, but this of course takes away a lot of the wireless appeal.

You can also use the mobile app to set different sound presets or you can put together your own setup. There are five frequency bands called Sub, Bass, Mid, Upper Mid and Treble, which can be raised or lowered. The frequency response is specified as 50 - 20,000 Hz, the crossover frequency is 3 kHz and the system should be able to generate a maximum SPL of 105 dB.

When it comes to operating time, the internally installed batteries are very impressive. The normal operating time is given as 20 hours, but this refers to continuous playback and of course also depends on the volume you use. Normally, the speakers should last for several days before they need to be charged again. In any case, I didn't feel the need to charge the product again during the test operation.

The AIAIAI Unit-4 in practice

When you look at the performance data of the AIAIAI Unit-4, it quickly becomes clear that the system was primarily designed for portable operation. Of course, you can also use these speakers as a second or third listener in a project studio or similar, but the focus on the small dimensions with maximum sound reproduction is always a sign of the portable operation approach. This operation can of course also be used as a small monitor during live shows. For example, they can be used as monitor boxes for DJs, keyboard players or other stationary artists. Because, it's hard to believe, despite their small dimensions and clear performance data, the speakers have a very large headroom and offer a comparatively balanced sound, especially in the lower and medium volume ranges.

In a neutral EQ setting, the speakers sound comparatively unspectacular. However, if you intervene a little in the sound control, the speakers are much more pleasing than is the case in the basic setting. Personally, I find the sub-band a bit pretentious, as in this range only the lower limit frequencies of the speakers are touched upon. However, the bass control is comparatively strong in its presence.

Due to the dimensions of the woofer, the speakers cannot really develop a high thrust. However, the woofer impresses with its relatively soft suspension in combination with the sophisticated bass reflex opening with an above-average definition of the bass range. Personally, I would be a little careful with the height control. If you give it a little more responsibility, the tweeter tends to sound relatively harsh, which can quickly ruin the otherwise well-balanced sound of the speaker.

Of course, you can never reflect the sound quality of the speakers in a test report, but you can compare them with other speaker designs. Compared to other portable monitor systems such as the KRK GoAux series, the AIAIAI Unit-4 really performs extremely well. Not only does the system impress in terms of sound with a somewhat more open reproduction, but also in terms of the elegance of the appearance, it is much more fun to work with loudspeakers with this look than with the sometimes somewhat clumsy micro speakers, which are also usually small The connecting cables on the back of the housing are pumped up to the limit.

However, with near-field studio speakers with a similar size specification such as the SC-204 from EVE Audio, the system inevitably has to lose out, as the AIAIAI Unit-4 speakers reach their limits here, especially in terms of their bass reproduction. The tweeter is also inferior to the Eve Audio speakers in terms of resolution. However, you can compensate for the bass range accordingly by using an additional subwoofer for the low bass range, which is probably what you generally do when working with satellites in the 4 inch woofer department.

However, you should always keep in mind that the price of the AIAIAI Unit-4 system includes an additional interface of the highest quality, which must be purchased additionally when purchasing another traditional near-field monitor system, unless you use the mini-jack output port, which is very sensitive to the touch of the Macbook want to use.

Conclusion

With the AIAIAI Unit-4, the Danish manufacturer has a wireless system in its portfolio that impresses with its elegant look, no-brainer handling and good basic sound. For me personally, it's an excellent choice for portable operation, as it requires extremely little space thanks to the included mini-interface and a simple, rudimentary travel case already offers enough protection for the system.

TEST: Eve Audio TS112

 In the end, quality prevails, or something like that you could summarize the career of the Berlin company Eve Audio in a very succinct statement. If you had asked me about this company almost 8 years ago, I would ultimately have had to pass, but my interest was piqued to the highest degree with my first test of this company's monitors. Eve Audio now has an impressive portfolio, from portable home recording nearfield monitors to powerful midfield “shooters”, which reach into the 1 KW range per loudspeaker box. It almost goes without saying that such a company also has appropriate subwoofers, which is why today we are taking a look at the “powerhouse” of the TS line, the EVE Audio TS112, which is the battleship in the deep bass range in terms of power output.

The conception of the EVE Audio TS112

The fact that a 12 inch woofer is installed in the EVE Audio TS112 gives an idea of the woofer's intended use. In contrast to live sound reinforcement, where a 12-inch speaker covers the low-mid range or even a classic 412 guitar cabinet, which uses a 12-inch speaker as a broadband speaker, with very few exceptions the same speaker size is the maximum you can expect in terms of subwoofer dimensions recording studio. In addition, the woofer has a peak power of almost 400 watts, so that the system can be positioned in the midfield area with the appropriate satellite equipment. If you are considering using a woofer and have a control room of up to approx. 20 square meters, you can actually save yourself the rest of this test report, as the physical conditions of the EVE Audio TS112 would exceed the possible uses in terms of the radiation behavior of a small control room.

As already mentioned, the playback is based on a single 12 inch speaker, which is clamped comparatively tightly due to the high power peaks, rests very firmly in its starting position due to the strong magnet and is equipped with a very massive surround. The membrane and dome are made of a very torsion-resistant material, which enables a frequency response of 24 - 300 Hz and a max. SPL @ 1m of 112 dB.

A major special feature of the Eve Audio subwoofer series, which is also present in the TS 112, is located on the underside of the housing. If you take a closer look at the pictures of the EVE Audio TS112, you will notice that the housing stands on four comparatively high feet, the unusual height of which immediately makes sense when you look at it from below. Perhaps some of the readers have noticed that the EVE Audio TS112 does not have a bass reflex opening. This “boost” solution from other manufacturers, which can sometimes generate a little wind noise when the loudspeaker is deflected higher, is achieved in the EVE Audio TS112 by means of a passive membrane, which is embedded horizontally in the bottom of the housing and of course has a certain amount of light for smooth operation Height required. Strictly speaking, the EVE Audio TS112 has two speakers, of which only one is actively operated.

  The back of the EVE Audio TS112

All connections of the Eve Audio TS112 are located on the back of the housing and are, as expected, in XLR symmetrical throughout, consisting of L / R - In / Out and LFE In / Out. A small extension of the labeling, but which makes it incredibly easier in practice, is the use of a regular and an upside-down labeling, where you can also read the labels if you lean over the woofer from the front to the back. Depending on the room, you may not always be able to walk around the woofer to carry out the correct cabling and in such situations a little thing like this is very helpful.


Furthermore, the woofer has 3 DIP switches, which can be used to activate various additional functions, such as:

Filter Lock: Securing the filters set on the front.
Volume Lock: Locks the volume set on the front.
Max. Input: Input sensitivity switchable between +8dBu and for studios with very high output levels +22dBu.

Finally, on the back of the housing there is the power plug, a voltage selector switch (220 - 240 V / 100 - 120 V) and the mains fuse.


The front of the Eve Audio TS112

The front of the Eve Audio TS112 is dominated by 2 rotary controls, which use a push function to guide you through the system's very extensive menu. In addition, 3 small LEDs provide information about different circuit states.

The lower rotary control takes over the function of the subwoofer volume in relation to the complete set and mutes the woofer using the push function. The LED ring around the controller works with an adapted mode of operation, which means that each LED has the following control depending on the volume:

-80dB (minimum) to -48dB: 2dB
-48dB to -20dB: 1dB
-20dB to 0dB (Maximum): 0.5dB

This useful logarithmic control allows a much more sensitive adjustment of the volume at high levels, while this fineness is not needed at low volumes. However, the sound control becomes really flexible when you use the upper control. The same controller takes over the overall control of the satellites and the woofer in terms of volume. First of all, it may be necessary to limit the satellites in the high pass so that the woofer is not put under too much strain on small satellites. Eve Audio recommends the crossover at 80 Hz, which is set as default. The same applies to the low pass of the woofer, which either transmits at 60 Hz up to 140 Hz or in LFE mode allows everything it can transmit.

In addition, the phase of the signal can be rotated if the room acoustics result in a disproportionately thin or booming sound due to phase cancellations. As with the other representatives of the TS class, Eve Audio has included an infrared remote control with the system, with which all functions can be controlled remotely from the control station. Especially when setting up the system for the first time, you can shorten the laborious “set-set-listen-get-up-go-change” repeat procedure and achieve significantly more effectiveness in a direct A/B comparison.

In practice

“That’s what I call a real deep bass,” these were the first words that came to mind when the first notes came from the EVE Audio TS112, but everything in order. Anyone who has previously worked with subwoofers with a diameter of up to approx. 8 inches may have to get used to the sound of the EVE Audio TS112, as the strengths of the woofer can only be measured on the second listening impression. Anyone approaching the situation expecting a higher volume due to the massive appearance of the woofer will be disappointed. At first impression, the subjective perception doesn't seem to differ that much from smaller woofers until you switch the woofer to standby and only hear the satellites alone.

Only now do you realize what the EVE Audio TS112 covers in the low and especially in the ultra-low bass range. Based on the strongly vibrating membrane, you could also visually see that a lot of air was being moved, but it was only in the A/B comparison that the woofer really came into its own. So how is it that this colossus is so incredibly subtle and discreet? In my opinion, the solution can largely be found in the passive membrane. As expected, the radiation behavior is still more or less circular, but the sound differs massively from a solution using a bass reflex opening. The sound of the EVE Audio TS112 is incredibly warm and unobtrusive, coupled with extreme headroom. If necessary, you can achieve the level of a real live sound system, which also allows you to test a club sound system at “real level” in the control room. In addition, there is a transmission that doesn't run out of steam even at 40 Hz, so that you can keep a perfect overview of the level, especially with bass-heavy music.

However, what should be very well coordinated is the crossover frequency with the satellites, which you should take a lot of time with. It can be assumed that if you use a 12-inch speaker in the bass range, you won't finish off with 4 or 5-inch speakers in the satellite range, as the "kink" in the linearity will be a little too strong. You can counteract the effect by having the woofer pass at 100 or 120 Hz, for example, but you should always be aware of the inertia of the bass speaker. Personally, I would complement this “jacket” with at least 6-inch, better still 8-inch bass speakers in the satellite range, which already provide a good bass foundation and add the EVE Audio TS112 as the ultimate bass controller.

Overall, you definitely have to give the EVE Audio TS112 the top rating, simply because there are no weak points in the system and the woofer holds up with incredible aplomb in all areas where a woofer can get sweaty. An absolutely top class subwoofer!


Conclusion

With the Eve Audio TS112, the Berlin company has a high-end studio subwoofer in its portfolio. The system has extreme power reserves, sounds incredibly discreet/subtle and, thanks to the passive membrane, produces a very unobtrusive basic sound with an outstanding deep bass reproduction, which extends right down to the very bottom of the frequency spectrum.

A professional subwoofer that consistently delivers even in large control rooms, hence top marks in all areas!

TEST: Eve Audio TS107

 The general public only became aware of them with the establishment of the surround sound system; today they can be found in almost every recording studio that does not work in a midfield monitor or larger area. We are talking about subwoofers that cover the sub-bass range for control purposes, which for physical reasons cannot be covered by nearfield monitors. For testing we have the smallest representative of the Berlin manufacturer Eve Audio, which is called the Eve Audio TS107 and could cause a lot of interest with a large number of special features.

The special features of subwoofer operation

Even though most users are likely to be familiar with the special features of subwoofer operation, here is a brief introduction for interested newcomers. While huge discussions are sometimes made about the placement of near-field monitors and the associated optimization of the stereo triangle (and rightly so), the optimal placement of a subwoofer is approached in a comparatively relaxed manner. Even a placement beyond the stereo center is still viewed very loosely, depending on the reflection surface near the woofer, as long as the actual area of ​​application of the system is not ruined by an unfavorable phase problem.

Why is that? The main reason is that the human ear no longer perceives any spatial location below approx. 300 Hz. It is therefore negligible whether the subwoofer is in the middle or to the side of the room, unless the unfavorable geometry of the room causes standing waves or something similar. The stereo image is formed exclusively by the satellites of the nearfiled monitors, especially since in almost all woofers the stereo signal is summarized in mono.

The advantage of a subwoofer lies particularly in the space-saving variant, as high-quality woofer operation allows you to achieve a deep bass that can otherwise only be achieved with very good and expensive midfield monitors, which also require medium to very large control rooms in order to exploit their full potential can. The danger of using a woofer, on the other hand, lies in the unoptimized coordination with the satellites, which then leads to an undifferentiated reproduction of the bass range and worsens rather than improves the sound reproduction. A good subwoofer is therefore not only characterized by an outstanding sound, but also by as many setting options as possible to ensure optimal cooperation with the satellites.

The construction of the Eve Audio TS107

The Eve Audio company has a total of 4 subwoofers in its portfolio, with the Eve Audio TS107 with its 6.5-inch bass loudspeaker being the smallest variant in the series. The softly suspended yet magnetically tight speaker offers an output power of 100 watts and has an internal limiter. According to the manufacturer, the frequency range is 33 - 300 Hz, whereby the woofer with dimensions of 230 mm x 355 mm x 300 mm and a weight of only 8.2 kg can be described as very handy. The maximum SPL is @ 1m: 102 dB. Like all other Eve Audio products, the Eve Audio TS107 is perfectly manufactured and offers no cause for criticism.

What I noticed when unpacking the product were the unusually high and massive feet on which the Eve Audio TS107 stands. A look at the underside of the case provides the explanation. Instead of, as is usual with almost all subwoofers, Eve Audio does without the bass reflex channel and instead uses a passive membrane, which compensates for the movements of the front speaker and the associated compression of the internal air, as well as working as a kind of second speaker. The result is a significantly tighter and more defined bass than the bass reproduction via the bass reflex channel, which sometimes tends to “slouch”. The flow noise caused by occasional air turbulence is also eliminated.

The connection panel of the Eve Audio TS107

All connections of the Eve Audio TS107 are located on the back of the housing and, apart from the unbalanced RCA connection, which was set up for the Eve Audio SC203 master/slave system, are symmetrical in XLR, consisting of L / R - In / Out and LFE In/Out. Various additional functions can be activated via 4 DIP switches, such as:

Filter Lock: Securing the filters set on the front.
Volume Lock: Locks the volume set on the front.
Auto On/Off: Auto standby mode if there is no signal at the input for longer than 10 minutes.
Max. Input: Input sensitivity switchable between +8dBu and for studios with very high output levels +22dBu.

The power plug is also located on the back of the housing.

The front of the Eve Audio TS107

The front of the Eve Audio TS107 is dominated by 2 rotary controls, which use a push function to guide you through the system's very extensive menu. In addition, 3 small LEDs provide information about different circuit states.

The lower rotary control takes over the function of the subwoofer volume relative to the complete set and mutes the woofer using the push function. The LED ring around the controller works with an adapted mode of operation, which means that each LED has the following control depending on the volume:

-80dB (minimum) to -48dB: 2dB
-48dB to -20dB: 1dB
-20dB to 0dB (Maximum): 0.5dB

This useful logarithmic control allows a much more sensitive adjustment of the volume at high levels, while this fineness is not needed at low volumes.

However, things only get really interesting when you take a look at the upper control. The same controller takes over the overall control of the satellites and the woofer in terms of volume. First of all, it may be necessary to limit the satellites in the high pass so that the woofer is not put under too much strain on small satellites. Eve Audio recommends the crossover at 80 Hz, which is set as default. The same applies to the low pass of the woofer, which transmits at 60 Hz up to 140 Hz or, in LFE mode, allows everything it can transmit.

In addition, the signal can be phased if the room acoustics result in a disproportionately thin sound. As a real luxury in this price range, Eve Audio has included an infrared remote control with the system, with which all functions can be controlled remotely from the control room. Especially when setting up the system for the first time, you can shorten the laborious “set-set-listen-get-up-go-change” repeat procedure and achieve significantly more effectiveness in a direct A/B comparison.

In this video, company founder Roland Stenz explains how the Eve Audio TS107 works:


The Eve Audio TS107 in practice

I am lucky enough to be able to use one of the satellite pairs recommended by Eve Audio in the test in my broadcast studio, the Eve Audio SC204, which is recommended for both stereo and surround sound. You can view a corresponding test here.

I chose the default settings with crossover at 80 Hz as the basic setting and was immediately impressed. The resulting sound turns out to be extremely voluminous, always defined and very discreet in terms of intrusiveness. However, the bass was a bit too subtle for me, especially since the SC204 can no longer deliver very strong acoustics above 80 Hz without additional boost functions. I therefore decided to separate the woofer at 140 Hz, which resulted in an incredible improvement in the bass and low-mid range.

The sound in this setting can really only be described as excellent, especially when you take the dimensions of the components into account. Especially in the project or home recording studio area, where every meter of space is important, the combination of small satellites, e.g. B. the SC204 and the TS107 generate a very mature sound, which is extremely rare given these dimensions. The combination of 2x SC204 and a TS107 costs less than €1,000, which seems downright ridiculous for this sound output.

Just for fun, I also set the woofer to LFE mode, but this was at the expense of the stereo image with the satellites because there was too much overlap in the midrange. After all, a 6.5 inch speaker is fast enough to transmit low mids from the guitar and keyboard sector well.

Conclusion

With the Eve Audio TS107, the Berlin manufacturer led by Roland Stenz has achieved a really big success. The extremely handy subwoofer impresses with extensive setting options, perfect workmanship and sophisticated detailed solutions, such as: B. a passive membrane, across the board and is therefore at the forefront when it comes to big sound solutions in the smallest of spaces.

Be sure to test it out and take your time setting it up individually, it's worth it!

TEST: ESP Will Adler Warbird

As a guitarist, it's not necessarily easy with the last name Adler. If the name in question is mentioned in a conversation with musicians, a respectful smile immediately spreads across the faces of drummers, especially if they have a connection to modern metal drumming. What is meant is the association with one of the current top 10 drummers in this segment, Chris Adler. Only a few people know his brother Will Adler, who was the rhythm guitarist in the band “Lamb Of God” and played with his brother in the same band for several years. Particularly due to its high level of popularity in the USA, the guitarist has several custom / signature models, of which we have by far the most expensive model, the ESP Will Adler Warbird Custom Shop Distressed, available for testing.

The concept of the ESP Will Adler Warbird Custom Shop Distressed

As with the other models made for Will Adler, the Warbird model is optically a Les Paul copy, which, however, differs significantly from the original in some details. The look of the test instrument in particular stands out due to its very distressed character and the huge “bone bird” sticker. However, the instrument has no claim to realistic wear and tear on the paintwork, as occurs with real vintage instruments; in fact, the paintwork was only very badly scratched.

The varnish was also artificially removed where no wear occurs during normal playing and the edges of the body binding, which should be smeared round at the armrest after such playing, are sharp-edged like those of a factory-new instrument. The hardware has been aged much more authentically. The pickup caps in particular have been beautifully trimmed to look old in terms of the uneven oxidation under and next to the strings, although here too the two caps were only copied and turned. A true vintage instrument will always have more wear and oxidation on the rear pickup cap of the bridge than that of the neck pickup.

What is a little strange given the massively used design of the instrument is the fact that, in contrast to the heavily scratched body and headstock, the neck is brand new and completely untouched. Somehow these two parts don't really fit together visually, but as always, it's all a matter of taste.

With a retail price of just under €7,500, the instrument is well outside the segment where one can speak of a realistic equivalent value even in metal; in fact, it is already very much in the enthusiast and fan section. But you should never forget that such visually unusual Custom Shop versions always represent a great advertising effect for the entire product range of an instrument type, i.e. even the lower-priced versions of the Warbird benefit enormously in terms of sales from the presence of an optical driving force.

The technical details

In the modern metal segment, there has been a clear shift in recent decades from the dominance of the solo guitarist to the appreciation of the rhythm guitarist. Just as current metal production is almost exclusively based on the principle of pressure, pressure and even more pressure, the current song material of many bands only focuses on powerful riff cascades, almost always in down or drop tuning. Where previously a wide carpet was rolled out for the soloist, who impressed the listener with an individual tone and extravagant scales in the high-speed range, today a guitar sound is usually generated that gets the maximum mass out of the high gain, sometimes so fat that it is already I have problems even being able to identify a bassist in the sound of a record production or a live show.

With the same in mind, Will Adler's tools are tailored to his function within his band, meaning the highest possible transparency even with maximum gain, good string separation within the riffing and a solid construction that can handle even harder attacks without intonation problems . The basis for this claim is the instrument's continuous, three-piece maple neck, which has glued-on mahogany wings and a maple top and, as expected, offers an extremely long sustain. Perfect for a strong solo tone, but unfortunately just a nice bonus in Will Adler’s role.

The fingerboard is made of ebony and has a scale length of 24.75". The shaping of the neck was dubbed “Thin U”, which sums it up quite well. The neck is quite slim and comparatively wide, fits well in the hand and will suit most players in terms of handling. All hardware was finished in “yellowed” gold, giving a sort of bronze feel to the base color scheme. Very nicely crafted, if the oxidation weren't so absolutely uniform, the look would be very close to real vintage hardware. If my interpretation is correct, small “warbirds” were used as fingerboard inlays.

6 Sperzel mechanics with locking function were used as tuners, which fulfill their function absolutely evenly and smoothly. Normal pins were used as belt pins, which will probably be exchanged very quickly by the user for locking mechanisms. In keeping with his function as a rhythm guitarist, a vibrato system was omitted; instead, the guitar comes with a classic bridge and a stop tailpiece. In order to avoid Gibson's legal letters, they didn't even try to use something bell-shaped as a truss rod cover, but instead opted for an oversized, cut-off "reverse bell".

Two Fishman Fluence pickups are used, which are manufactured according to Will Adler's specifications. Unfortunately, it was not possible to find out whether these are technical changes that also influence the Klamg, or whether it is just the visual aspect that creates the signature character. Like all Fishman Fluence pickups, the pickups here have 2 different sound characteristics, with one being slightly more active and the other being more passive. These are switched using a push/pull potentiometer, in this case it is the tone control on the guitar. In addition, each pickup has its own volume control.

The power supply for the pickups is a special feature. As with other manufacturers who offer their instruments in the high price segment, the pickups are powered by a battery, which is charged via the combination of USB plug / mobile power supply. A good thing, which reduces battery waste, although the built-in battery will of course have to be disposed of at some point.

The ESP Will Adler Warbird Custom Shop Distressed in practice

It is questionable whether the ESP Will Adler Warbird Custom Shop Distressed will ever be connected to a clean channel, which actually turns out to be a shame. Depending on the setting used, the instrument can also generate very pearly, clear sounds in the various pickup constellations, especially if you use passive emulation of the pickups.

But it is also a fact that every orchestra leader or even the buddies from the local jazz quartet would get green pimples if they dared to appear at a public performance with an instrument that has these optical qualities. In return, anyone who deals with truncated half-waves will at least be left with a respectful “Oha” as soon as you take the instrument out of the supplied case.

How much of the unusual finish will reach the audience in the dark stage light is another matter, but in terms of sound, the ESP Will Adler Warbird Custom Shop Distressed delivers exactly what the optics promise. The entire construction delivers a differentiated sound even at maximum gain, combined with excellent vibration behavior. The touch more maple generated by the continuous neck also ensures a touch more freshness in the basic sound than the mostly low-mid-based sound generated by the classic mahogany neck / mahogany body combination.

Conclusion

With the ESP Will Adler Warbird Custom Shop Distressed, the Japanese company delivers an instrument that acoustically and, above all, visually meets almost all the trademarks that a high gain protagonist should fulfill. Anyone who likes to spend time in modern metal realms will find this instrument an excellent tool that shines with clean string separation, great assertiveness and outstanding sustain.

The fact that the artificial aging of the instrument only serves coolness factors and in no way corresponds to real wear and tear should be noted just as coolly and be happy for the enthusiastic owner. After all, this is not about an authentic blues tool, but rather a visually and acoustically outstanding instrument for the ambitious metalhead. In addition, anyone who can lighten their wallet by almost €7,500 for a single instrument is a very happy person anyway.

TEST: ESP Eclipse QM

 Some test instruments seem to have an air of something special about them, simply because there is hardly any information material about the instrument. So I'm holding the ESP Eclipse QM TEASB Duncan in my hands and both the look and a few brashly played chords suggest that it's a very special instrument. I am excited.

The construction of the ESP Eclipse QM TEASB Duncan

“Another Paula copy” I can already hear the first complainers saying and yes, you can't dismiss the fact, the instrument is actually a very clear one, apart from a few details that were changed out of fear of the Nashville lawyer armada Copy of one of the largest trademarks in the field of electric guitars. But wait, some points don't seem to correspond to the larger model. Let's take a closer look.

Let's start with the typical features of a Les Paul, e.g. B. the body, which, as expected, was made of mahogany. According to internet research, the body is “chambered”, meaning that cutouts have been made in the body to reduce the weight. As a rule, I am not a fan of these measures, especially since Gibson has made a big mistake with this measure in recent years, as the resonance behavior of instruments of this design has deteriorated significantly. With the ESP Eclipse QM TEASB Duncan, however, this behavior cannot be observed, especially since the instrument still weighs just under 4 kg. Without the hollows we would probably have arrived in the good old early eighties, where a Paula weighed over 5 kg. I love these menhirs, but that's another topic.

Normally, a glued neck made of mahogany would now appear on the screen, but this does not match the grain of the neck base at all. And in fact, the instrument is based on a continuous, three-part neck, which sits in a pocket throughout, so that the bottom of the ESP Eclipse QM TEASB Duncan is still around 1.5 cm continuous and not the body wings as with comparable instruments were completely glued on. By the way, the body is in one piece, as far as the grain pattern suggests. The result of this unusual construction is an almost unbelievable sustain, which even the cutouts in the body cannot harm.

Another special feature of the ESP Eclipse QM TEASB Duncan is the shaping of the body, which significantly increases the playing comfort compared to the hard edges of a Paula in the belly fat area. The ceiling used is an exceptionally beautiful, two-part bookmatched maple top from the brand “Wölkchenahorn”, which allows for an almost three-dimensional resolution depending on the angle of incidence of the light. The same look was continued on the top of the headstock. The fingerboard is made of ebony and offers the classic short scale length of 24.75 inches / 629 mm with 22 frets from the JESCAR FW57110 XJ Stainless brand. In order to increase the stability of the neck against the infamous “skull base fracture” compared to the saddle due to the structural weakening caused by the truss rod, the classic “knubble” was created at the transition to the headstock.

Curved block inlays are used as fingerboard markings and in order to underline the origin of the otherwise mainly made in Japan, the characters “ESP USA” were embedded in the 12th fret, which also explains the ambitious price of around €4,200. No savings were made on the hardware either; instead, in addition to locking mechanisms from Sperzel, they were used as a bridge/tailpiece. The currently very popular TonePros T3BT Locking TOM with T1Z Locking Tailpiece is used. The strap pins were once again provided by Schaller, the corresponding counterparts for the strap are included with the instrument. Everyone has to decide for themselves whether the bones of dead animals will still have to be used as saddles in 2020.

The pickups used were Seymour Duncan pickups, unfortunately I couldn't find out which model was used. Due to the price segment, it could be Alnico Pro-II humbuckers, but this statement is only an estimate. The instrument has 2 volume controls and a tone control, the latter of which is available as a push/pull version and the humbucker can be switched to single coil. The instrument comes with an upscale molded case.

In practice

I admit, there are rarely moments when I, as a tester, get excited before the instrument has even been connected to the amplifier, but here we have such a case again. It's incredible what sustain the instrument delivers even in the dry dock. Whether single tones or chords, the extremely fast response and the almost endless decay behavior immediately captivates me, especially since my personal main instruments throughout my life have been either Les Pauls or comparable instruments such as: B. my current Framus Panthera custom guitars were, or are. Even if you were to install the cheapest Far East pickups on this instrument, it would be difficult to mess up the excellent basic sound of the instrument.

The playability of the ESP Eclipse QM TEASB Duncan, as well as the weight reduction, have once again been trimmed towards “comfort”, i.e. the neck profile has been optimized towards a “Thin U”, which clearly benefits the instrument’s comfort. ESP has really cleverly implemented this approach. Normally, a solid body and a correspondingly “meaty” neck have an effect on the sustain behavior of the instrument. However, if the construction already exhibits such high-quality vibration behavior, you can still remove some of the wood fibers from the instrument to make it easier to handle.

The factory settings of the instrument were so well done that nothing had to be readjusted. The set of strings was a standard 10 (010 - 046), which suits the instrument well. In general, I am of the opinion that classical guitar types should be equipped with at least a set of 10, the dynamics and volume will thank you for it. 009 or similar should be reserved for the Floyd Rose Dive Bomb camp.

I was curious to see whether the ESP Eclipse QM TEASB Duncan could also convey the excellent, unamplified sound through the loudspeaker and experienced one or two surprises. To be honest, in my opinion the nameless Seymour Duncan pickups can't quite maintain the construction quality, which surprises me even more since I've always been a big SD fan. Both the neck and bridge pickups offer a much tighter treble response than one would generally expect from an LP copy. The result is not bad, but offers a comparatively “bitchy” sound in humbucker mode. Whether you like this basic sound is purely a matter of taste, so I would like to ask every interested musician to form their own opinion.

What didn't convince me, however, was the single coil circuit of the pickups. Of course, the output power of a single coil pickup is usually lower than that of a humbucker, but the amount of power lost here is quite striking. It feels like 50% of the signal falls by the wayside and not only leaves a significant drop in volume, but unfortunately also an associated thin and pointed sound that does not do justice to the quality of the instrument.

In any case, nobody would think of joining a chic tribute band with an instrument of this design, but in this case, in my opinion, various points come together that stand in the way of high-quality single coil operation. The choice of wood, the short scale length and the somewhat unfortunate choice of pickup don't really make this sonic extension shine. It would therefore be worth considering whether this circuit should not be discarded entirely, especially since the reduced circuit effort would benefit the general sound of the instrument.

Otherwise, the ESP Eclipse QM TEASB Duncan impresses across the board with the vibration properties already mentioned. The solo tone swings out very nicely and can score particularly well in the crunch and lead areas. Higher levels of distortion up to the high gain range are possible, but are not necessarily one of the best things about the ESP Eclipse QM TEASB Duncan.

Conclusion

With the ESP Eclipse QM TEASB Duncan, the Japanese manufacturer offers a top-class instrument in terms of vibration technology. The sustain and general vibration behavior are of the highest quality, the workmanship is flawless, and the appearance is appealing.

Depending on the area of application, the customer may need to check the pickups based on their personal taste, which sound by no means bad, but very special in the overall context.

Introduction:
In the dynamic world of musical instruments, few companies have left as indelible a mark as ESP Guitars. Renowned for their exceptional craftsmanship, innovative designs, and unwavering dedication to musicians' needs, ESP has carved out a significant niche in the guitar market. However, the journey of ESP Guitars from a humble repair shop to an international icon is a story rich in history, perseverance, and passion.

Early Beginnings:
The origins of ESP Guitars can be traced back to the bustling streets of Tokyo, Japan, in the late 1960s. It was during this time that Hisatake Shibuya, a skilled luthier with a deep appreciation for quality craftsmanship, established a small shop called Electric Sound Products (ESP). Initially, the company focused on providing custom guitar repairs and modifications, catering to the burgeoning rock and roll scene in Japan.

The Rise of Customization:
As the demand for customized guitars grew, ESP quickly gained a reputation for its meticulous attention to detail and willingness to accommodate the unique preferences of musicians. This commitment to customization became the cornerstone of ESP's identity and set them apart from other guitar manufacturers of the time. Musicians flocked to ESP for bespoke instruments tailored to their specific playing styles and aesthetic preferences.

Collaborations with Iconic Artists:
One pivotal moment in ESP's history came in the late 1970s when the company forged partnerships with influential Japanese musicians, including Japanese rock icons such as Char and KISS frontman Paul Stanley. These collaborations not only elevated ESP's profile but also solidified its reputation for quality and innovation within the music industry.

Expansion and International Recognition:
Throughout the 1980s, ESP continued to expand its reach both domestically and internationally. The company's reputation for crafting high-quality instruments caught the attention of musicians around the world, leading to an increase in demand for ESP guitars beyond Japan's borders. This prompted ESP to establish distribution networks in key markets such as the United States, Europe, and Southeast Asia.

One of the defining moments for ESP's international recognition came in the mid-1980s when Metallica's lead guitarist, Kirk Hammett, began using ESP guitars. Hammett's endorsement of ESP solidified the brand's association with heavy metal music and propelled its popularity among metal guitarists worldwide. Other notable artists who endorsed ESP during this period include George Lynch of Dokken and Bruce Kulick of KISS, further cementing ESP's status as a premier guitar manufacturer.

Innovations in Design and Technology:
ESP's commitment to innovation has been a driving force behind its success over the years. The company has continually pushed the boundaries of guitar design and technology, introducing groundbreaking features that cater to the evolving needs of musicians.

One such innovation was the introduction of the ESP Horizon series in the late 1980s. The Horizon series showcased ESP's expertise in crafting high-performance guitars with sleek, modern designs. These guitars featured innovative hardware, such as Floyd Rose tremolo systems and EMG pickups, which appealed to shredders and heavy metal guitarists seeking maximum playability and tone.

In addition to its electric guitars, ESP also made significant strides in the development of bass guitars. The ESP Precision Bass and Jazz Bass models became popular choices among bassists for their exceptional tone, playability, and durability.

ESP's commitment to innovation extended beyond instrument design to include advancements in manufacturing techniques and materials. The company invested in state-of-the-art facilities and employed cutting-edge production methods to ensure consistent quality and precision in every instrument.

As the company looks towards the future, it is poised to remain a leading force in the world of electric guitars, inspiring musicians and shaping the sound of generations to come.

TEST: ESI uniK Plus

 OK, I admit it, I'm a fan of product care. In my opinion, it simply makes more sense to optimize a product that is running well in the second or third attempt and to respond to customer suggestions than to repeatedly bring new product series onto the market in comparatively short time intervals. Those responsible for ESI probably thought of the same and brought the ESI uniK 05 plus, the successor to the normal 05 series, onto the market.

In order to justify the four letters behind the product name to the user, much more than just optical cosmetics was carried out, but everything in order.


construction

The monitor looks pretty. The combination of the colors black and copper in combination with the matt, rounded front is definitely pleasing to the eye. The type designations and the white lettering on the back are also in this color, which creates a touch of corporate identity. Tastefully! The box comes with 4 rubber feet, which are not only intended to decouple the housing, but can also adjust the angle of inclination upwards and downwards using appropriate screw axes.

ESI really doesn't make it easy for itself, as the monitor series, with a retail price of around €189 and Chinese production, is in a broad segment of competitors in the budget class. In order to stand out from the competition, you need a lot of special features to get the buyer's attention. With the dimensions (W x H x D): 190 x 265 x 210 mm and a weight of just under 4.4 kilograms, they are still in the normal range and the beautiful, copper-colored 5 inch Kevlar woofer is not too noticeable either very out of the norm, but wait, the tweeter doesn't just differ visually from the usual dome tweeters.


extravagant tweeter

Anyone who feels briefly reminded of the competitor ADAM Audio is ahead. As with the aforementioned competitor, the ESI uniK 05 plus uses a ribbon tweeter, the equivalent of a ribbon microphone. As with the microphone version, the tweeter is characterized by extremely good impulse behavior due to its very low mass. Unfortunately, the tweeter also shares the same problems as a ribbon microphone. Both are known for their high sensitivity to external mechanical influences. In order to protect the tweeter as comprehensively as possible, ESI not only placed a steel grille on the front, but also installed a fine-meshed net, which is also intended to counteract moisture and fine dirt.


upgraded back

In order to reinforce the difference to its predecessor, ESI has dedicated the Plus variant in particular to optimizing the room acoustics. The product has an unusually large selection of optimization points in this price range, starting with a two-band tone control, which has an amplification factor of +/- 5 dB each. The preamplifier, on the other hand, even allows +/- 14 dB, which means the system can be adapted to pretty much any output voltage. What is really unusual, however, is the “Character” control, which allows you to seamlessly raise or lower the entire frequency spectrum from approx. 50 Hz by +/- 6 dB. The manufacturer refers to these control paths as “Smooth” or “Bright”

Due to the recessed arrangement of the potentiometers, all settings are made using a mini slotted screwdriver, which was included in the box. Applicable signals can be fed in via XLR or TRS via the combination socket, which should be sufficient for 90 percent of all applications. The switchable standby function saves energy and puts the box into sleep mode after several minutes without a signal. A ground lift is also available for ground loops or inadequate power supply abroad.

ESI has come up with another special feature for the reflex opening. The opening again on the top edge of the housing can be completely closed with a tightly fitting foam plug. This is to ensure that the speaker is not prone to the infamous booming frequencies in the bass range when placed near a wall, or even worse in a corner of the room. Interesting detailed solution.


Practice

According to the enclosed operating instructions, the ESI uniK plus has a frequency response of 49 Hz - 25 kHz. Even if the values do not allow for a real evaluation, you can still see the system's preferences. No one expects “real” bass from a 5-inch bass speaker without subwoofer support, but you should keep in mind that in this case an approximately linear bass transmission only begins at around 70 Hz. Therefore, please do not give in to the misconception that the system can reproduce bass guitars, kick drums or electronic instruments in the bass range in a balanced manner.

I also strongly advise against misusing the two-band tone control as a booster in the bass range; unfortunately the limits of physics cannot be exceeded. Increasing it using the bass control only resulted in more choking in the impulse behavior, which even the fast and stiff Kevlar speaker couldn't absorb. If you don't succumb to this malpractice, you will get a well-defined bass tone that can be located very well, but nothing more. The system cannot develop a real punch.

There are no complaints to note in the midrange. Rather, I liked that the crossover frequency of 3.2 kHz was well chosen and that the infamous center hole did not appear in the crossover. In terms of sound, the box tends to produce a tight reproduction without too much harshness, but also without the flattering effect that is reserved for the next higher price ranges. The stereo imaging of the system, on the other hand, is excellent; if the speakers are positioned optimally, nothing is left to be desired in terms of depth and location behavior.

Yes, and then there is the highlight of the system, the treble reproduction of the ribbon tweeter. I would like to do this again show an analogy to the ribbon microphone. Just as the sound of the microphone type of the same name divides users into two camps, this type of tweeter will also cause never-ending discussions. As expected, the tweeter is characterized by extremely fast reproduction and is also largely responsible for the very good stereo positioning.

In return, the tweeter sounds significantly sharper than the average dome tweeter, which allows the user to reach for the high-mid control relatively quickly and also reduces fatigue while listening. A considerable amount of listening time is necessary to get used to the system's frequency curve. Unfortunately, it is not the “whispering” highs above 10 kHz that would possibly lead to excessive shimmering, but rather the “biting” high-mids above the 4 kHz limit, to which the human ear is already hypersensitive.

However, if you are aware of these points and have adjusted your hearing accordingly, you can work with the ESI uniK plus in a very practical way. The plus points clearly outweigh the negatives and make the system a good second/third listening device or a high-quality first listening device at the DAW station in the project studio.



Conclusion

With the ESI unik plus, the system receives a high-quality upgrade compared to its predecessor. A lavish sound control in combination with several well thought-out detailed solutions makes the visually sophisticated box a real asset in the project studio.

Everyone has to decide for themselves whether they like the sound of the ribbon tweeter, but the comparatively harsh tweeter reproduction is matched by extreme impulse fidelity and excellent stereo positioning.

Definitely worth checking out in person!

TEST: Epiphone JC LP Custom

 How times change. While the earlier signature instruments of established artists were usually the most expensive instruments in the respective manufacturer's portfolio and were often manufactured by the most talented Luthiers in the company group, the way of thinking and manufacturing has changed in this regard in recent years. almost diametrically opposite. The classics in the portfolio are now often manufactured in the manufacturer's home country, while the signature models are often manufactured in the Far East at cheaper conditions. Similar to the ESP / LTD constellation, for example, the big name Gibson has the subsidiary Epiphone, which was once one of the big names in the jazz sector, but has now been established as the mainstay in the budget class for Gibson. As a test instrument we have the signature model of the “Alice In Chains” guitarist Jerry Cantrell, which is made in China and is called the Epiphone Jerry Cantrell Prophecy LP Cus.

The concept of the Epiphone Jerry Cantrell Prophecy LP Cus

As a subsidiary of Gibson, the trademark Epiphone is, as expected, allowed to use all optically protected elements of the parent company, so that the Les Paul version hardly differs visually from the original in terms of its curves, apart from the independent headstock. Only a few small details were changed in favor of the slightly modified Signature version, but these only show a marginal difference.

The instrument, which is kept in “Bone White” throughout, including the binding, is visually very striking and, like any other white instrument, has the advantage that any colored irradiation from stage spotlights is absorbed 1:1. Ultimately, you have to decide for yourself how much you like the color scheme, but the instrument at least benefits from the truism “If You Wear Black, You Have To Play White”. Personally, I find the discrepancy between the “old white” binding and the very light “bone white” a bit too strong, as the binding always looks a bit “dirty”, but as I said, it's all a matter of taste.

As expected, the basic construction of the Epiphone Jerry Cantrell Prophecy LP Cus was largely taken over from the original Les Paul, so the dimensions of the body, scale length, etc. are identical. What is immediately noticeable, however, is the comparatively low weight of the guitar, which at around 3.4 kg is significantly less than the weight of a classic LP. In the info sheet for the guitar, the negative word “Chambered” is avoided; instead, the term “Ultra Modern” is used for “Weight Relief”, which in my opinion probably suggests that the body is hollowed out. As long as the vibration behavior does not suffer as in the Chambered versions of the first generations, there is nothing wrong with reducing the weight, otherwise here too, it is up to you as you please.

To list the respective Les Paul configurations in detail here again would mean carrying owls to Athens, as every musician has probably held a Paula in their hands at least once, or should hold it at least once, in order to understand the significance of what happened almost 70 years ago the most famous signature model of all time (yes, the Les Paul is a signature model!). The choice of wood, scale length, construction and feel correspond to a large extent to a white Les Paul Custom from the eighties, which, however, came without any weight reduction at the time and often nibbled at the 5 kg mark and more.

The differences to the original Les Paul

But apart from the weight, what exactly are the differences to the original Les Paul so that the AIC guitarist's special requests were fulfilled. Let's start with a detail in the form of Grover Locking Rotomatic tuners, which, in conjunction with the Graph Tech saddle, enable smooth and clean tuning. The “Circle in Diamond Custom Inlays” and the, let’s say very “feminine” in a kind of Signed Roundhand designation of the guitar on the truss rod cover are just as individual.

The biggest difference, however, is probably in the area of the pickups, where the Epiphone Jerry Cantrell Prophecy LP Cus consistently placed emphasis on active alignment. Once again the Fishman Fluence pickups were used, which are now used very frequently, especially in the hard'n'heavy sector, and sometimes have a strong impact on the chair leg of the previous top dog EMG. Which pickups you ultimately like better is once again a matter of taste, but many users often mention the possibility of two different voicings within the pickup network as a pleasant feature.

In order to be able to use the comprehensive tone control of the pickups without losing the classic tone control of the Les Paul in the form of 2x Tone and 2x Volume, they chose “2 Volume with Push/Pull Coil Splitting, 2 Tone with Push/Pull Pickup “Voice Switching” was chosen, in which, in addition to the voicing selection of the individual pickups, the pickups can also be switched to sigle coil operation via an individual coil tap. Unfortunately, three of the four potentiometers show a comparatively indirect control, i.e. a small moment always passes before the potentiometer axis engages in the housing after it has been rotated. Not really a big problem, but it takes some getting used to for guitarists who like to use the volume control to control the interaction with their amplifier.

In order to be able to operate the preamplifiers of the active pickups, the Epiphone Jerry Cantrell Prophecy LP Cus also requires a 9V block, which must be placed in a way that is as easy to maintain as possible. To avoid the “battery wrapped in foam stuffed into the electrical compartment” solution of earlier days, Epiphone uses a snap lock inside the electrical compartment cover, which unfortunately doesn't convince me in several ways. On the one hand, the construction appears comparatively “plastic-like”, and on the other hand, the solution “a drawstring with a battery that can be clamped tightly plus a freely dangling 9V battery clip” is a solution that, in my opinion, is not worthy of a signature model, unless this solution This happened at the express request of the guitarist, which of course I cannot judge.

What also seems a little strange in my opinion is the fact that the instrument was delivered without a 9V battery. Maybe it was just forgotten, maybe those responsible are worried about a leaking battery, but at least the inclusion of a 9V block should be part of the instrument's standard equipment. At least there is plenty of space for it, as the Epiphone Jerry Cantrell Prophecy LP Cus is delivered in a high-quality, black hardshell case.

The Epiphone Jerry Cantrell Prophecy LP Cus in practice

Even when played in an unamplified state, you can see that the weight reduction does not have a negative influence on the vibration behavior of the instrument. The guitar has a subtly hollow sound character, but that shouldn't be viewed in a judgmental way. However, the instrument is not optimally set up at the factory, which is noticeable in the buzzing E1 strings above the 10th fret. Nothing that you can't fix yourself with a few simple steps, but if you're going to put a sticker saying "Handcrafted In China" on the back of your neck, I think you have to deliver accordingly when it comes to craftsmanship.

The strong neck feels pleasant in the hand and offers very good playing comfort, especially when things need to get a little more hearty. The instrument's attack and decay behavior is good and the response is quick. Due to its low weight, the guitar is easy to handle and will be a lot of fun for all users who are looking for the most comfortable stage feel possible.

In terms of sound, the Epiphone Jerry Cantrell Prophecy LP Cus offers an excessive range of sounds for an LP modification due to the pickup construction, which goes well beyond the 3-way options of a typical LP standard or custom. Although as the level of distortion increases, only nuances in the sound spectrum are perceptible, but in the clean and crunch area, a comparatively large number of tonal variations can be created with the two voicings and the single coil circuit, although, as with all coil taps in the humbucker area, the single coil circuit is not the same Can offer character like a pure single coil pickup, which is the case with every humbucker of this type.

If you are looking for the typical low-mid range of a classic Les Paul, possibly thickened with EMG pickups, you should check the Epiphone Jerry Cantrell Prophecy LP Cus in advance to see whether it meets your sound expectations. The guitar undoubtedly sounds very good, but the sound is in slightly different regions than you are used to from a Paula. This can offer advantages or disadvantages depending on what you are looking for.

Conclusion

With the Epiphone Jerry Cantrell Prophecy LP Cus, the Gibson subsidiary has a model in its ranks that has a slightly different sound than what the appearance suggests. Due to the pickup and wooden construction, the guitar offers a high-quality basic sound, which is very well established in the sound and ensures a high degree of independence, but is clearly different from a classic Les Paul.

From its humble beginnings in the late 19th century to its current status as a global guitar powerhouse, Epiphone has played an integral role in shaping the landscape of modern music. Let's delve into the captivating journey of Epiphone, tracing its origins, pivotal milestones, and the iconic instruments that have cemented its place in the annals of guitar history.

**The Early Years:**

The story of Epiphone traces back to the bustling streets of Smyrna, Ottoman Empire (now Izmir, Turkey), where Greek founder Anastasios Stathopoulos began crafting instruments in the late 19th century. Initially specializing in the construction of traditional Greek lutes and violins, Stathopoulos honed his skills and soon expanded his repertoire to include mandolins, banjos, and eventually guitars.

In 1903, Stathopoulos immigrated to the United States and settled in New York City, where he continued his craft under the brand name "The House of Stathopoulo." The company quickly gained recognition for its superior craftsmanship and innovative designs, attracting a growing clientele of musicians seeking high-quality instruments.

**The Rise of Epiphone:**

In 1928, Anastasios' son, Epaminondas "Epi" Stathopoulos, took the reins of the family business and embarked on a mission to propel the company to new heights. Under Epi's visionary leadership, the company underwent a rebranding, adopting the name "Epiphone" as a tribute to its founder and embracing a newfound focus on electric guitars.
