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.

TEST_ Seymour Duncan Powerstage

 Times have changed. Features such as portability, weight and dimensions have become massively more important in recent years. Along with a few other suppliers, Seymour Duncan has also responded to this trend and launched the Seymour Duncan Power Stage 170 and the Seymour Duncan Power Stage 700, two power amplifiers designed specifically for guitarists and designed for portability.

The concept of the Seymour Duncan Power Stage series

50 years ago, everything was very simple. Due to a lack of PA systems, you packed as many 412 cabinets and heads as you could get into a van or truck, set them up, switched them ALL on and filled the entire hall with sound from the stage. The end result: an excellent guitar sound and deaf musicians.

Those days are definitely over and not even the most die-hard vintage fans of recent times want this sound system back. The exact opposite is the sound constellation in which all musicians play directly into the desk using modeling amps and D.I. boxes and you can no longer hear any other instrument on the stage except the direct radiation of the drum sound. A dream for hall mixers, but the interaction between the guitar string and the moving air of the loudspeaker is lost. The result is a comparatively lifeless sound, which sometimes makes old-school musicians feel a kind of disgust.

The middle ground that is increasingly sought after is a mixture of both systems, i.e. you generate enough sound pressure on the stage using a comparatively quiet and small system to enable interaction with the instrument, but get the final volume from the individually adjusted in-ear system. Never before have so many 1x12" or 2x12" boxes been seen on stage, even in the harder faction, while the full-stack armada that is still often lined up to fill the stage mostly consists of empty dummy housings for weight reasons.

In order not to ruin the transport advantage by lugging around heavy all-tube tops, you need power amplifiers that are as small, light and good-sounding as possible, preferably the size of a stomp pedal and that can be connected directly to the floorboard if necessary. Do I see the first people pricking up their ears?

The Seymour Duncan Power Stage 170

The Seymour Duncan Power Stage 170 is a 170 watt Class D power amplifier aimed at two groups of musicians who both have the same concern or problem. It's about size and weight (as is always the case in life...). With dimensions (L x W x H): 292 mm x 176 mm x 56 mm and a weight of just under 2.8 kilograms, the power amplifier can actually be placed on the floorboard and secured with Velcro / cable ties.

This means, conversely, that with the right concept, you can leave your regular top at home and travel with just the floorboard, speaker and guitar. If you can find a working cabinet on site, or you share equipment with other bands on site, you can even travel to the show by public transport.

The second target group are professional musicians who often have to travel by plane to shows abroad. I myself know the problem well enough that, depending on which country you are playing in, the organizers only provide you with completely worn-out material in which not a single amplifier works perfectly. My personal "highlight" was the penultimate Russia tour, tour stop St. Petersburg. Three Marshall tops on site, one with a broken master volume control, one with oscillating power tubes and one that wouldn't turn on at all. Taking a "mini amp setup" with you in your personal suitcase can minimize many problems.

Some people will now rightly ask why the power amplifier has such a high output. It must be said that this value only applies to 4 ohms and, unlike a tube power amplifier, the power decreases with increasing ohm count. At 8 ohms, the power should be around 90 watts, at 16 ohms around 50 watts. But don't worry, always remember that to double the volume, the power must be increased tenfold, i.e. 170 watts is only just twice as loud as a 17 watt amplifier.

The Seymour Duncan Power Stage 170 is very simple in its design, which didn't stop the manufacturer from packing the product in a very attractive housing with a brushed aluminum top. The product, made in the USA, has a clean preamp and a three-band tone control that starts at frequencies of 87 Hz, 712 Hz and 6.61 kHz and allows a boost/cut of 13 dB. A large, protruding volume control allows you to adjust the volume with your foot during the show; theoretically, you can also raise the volume for a solo and then turn it back down on the fly. A powerful fan on the front ensures that the internal components are cooled. On the back there is an input and output, a power plug, an on/off switch, and that's it.

The Seymour Duncan Power Stage 170 in practice

The fact that the Seymour Duncan Power Stage 170 does not have any rubber feet alone shows that the entire concept is designed for pedalboard operation. The built-in preamp means that you can actually connect your pedals directly to the power amp and treat it as if it were the clean channel on your personal amplifier. Put bluntly, overdrive in front, distortion in front and you have a three-channel amp.

If you don't need any distortion for your sound, you can even plug the guitar directly into the power amp. Jazz musicians will be happy! There's also a tuner and you can go to the show with 2 pedals, or even just one with a clamp tuner. For my part, I took a three-channel Koch Amps Superlead pedal, connected a Line6 Pedal Modeler to the Superlead, sent the whole thing directly to the power amp and attached a 412 Marshall cabinet with 75 watts Celestion to the back.

It really made my jaw drop. I placed just 3 pedals on a small pedal board with a total weight, including all power supplies and cables, of less than 8 kilograms, and I got a sound that beats many high-quality all-tube tops. The sound is powerful, dynamic and yet subtly compressed, with the three-band tone control responding very well to the respective orientation of the speakers. The tone control works very tastefully, although the bass control is a bit too low for the standard tuning, but it can fully exploit its strengths with ERG guitars. At high volumes there is even a hint of saturation, which is very subtle and never initiates the notorious "transistor distortion".

The Seymour Duncan Power Stage 700

The big brother of the 170 power amplifier enters the stage with the Seymour Duncan Power Stage 700. I'm going out on a limb here. Even if the product is advertised as a pure guitar power amplifier, all the connections suggest that electric bass players could also find a home here. 700 watts at 4 ohms will destroy any normal guitar cabinet and even if the cabinet has 8 ohms, the approx. 350 watts are beyond good and evil. 16 ohm speakers are not supported. Bass players are more relaxed about such power outputs, however, as stable bass reproduction requires significantly more power reserves than the guitar spectrum.

The two outputs in Speakon / jack combo sockets in conjunction with the 4 / 8 ohm speaker specification also show a clear bass cabinet orientation; Speakon is actually not available in guitar speakers. Otherwise, the concept of the Seymour Duncan Power Stage 170 has been transferred to the 700 version, although the Seymour Duncan Power Stage 700 is a stereo version that also has an XLR connection to the FOH, which can be used for speaker simulation if required.

It is also great that the 700 has a multi-voltage power supply, which makes the power supply much easier for international performances. The power amplifier can also be installed in the rack using 2 rack angles, where it takes up less than 2 U.

Conclusion

With the two power amplifiers Seymour Duncan Power Stage 170 and 700, the American manufacturer is dedicated to the very specific target group of modeling amp players and working musicians. Both groups are supplied with very good-sounding products and a detailed range of features, with Seymour Duncan managing to generate a completely new type of transportability, particularly with the 170 version.

While the 700 version still raises a few small question marks for guitarists (high power output, only one volume control for 2 channels, Speakon outputs), the little sister convinces as an excellent niche product that many musicians have been desperately waiting for.

Top marks!

TEST: Seymour Duncan Hyperswitch

 I can still remember quite well how around 40 years ago, the majority of guitarists succumbed to a tinkering urge with their pickups that had never been seen before. Up until then, people had been completely satisfied with the factory options of a 3- or 5-way switch, but at some point the first desires arose, for example to connect the bridge and neck pickups of a Strat together, or to try out how a Paula sounds with a single coil circuit. This trend culminated in constellations where a multitude of toggle switches, mini-switches and push-pull potentiometers were placed on the guitar with 3 freely combinable pickups and a serial, parallel, out-of-phase and single coil circuit, which made the guitar top seem more like a kind of cockpit than a surface. In addition, every switching process required a lot of mental effort and dexterity, which sometimes greatly distracted from personal playing. Seymour Duncan wants to counteract this fiddly work with its Seymour Duncan HyperSwitch by designing a programmable 5-way switch that combines all optional switching functions of pickups in one switch.

The concept of the Seymour Duncan HyperSwitch

The Seymour Duncan HyperSwitch is a classic 5-way switch that can be easily used in models that already have such a switch when they are delivered. In order to save the different switch positions, the Seymour Duncan HyperSwitch requires a 9V battery, which should find its place in most switch / pickup millings. For custom-made models, however, a further check is advisable to be on the safe side. As expected, the Seymour Duncan HyperSwitch only works with passive pickups, as the electronics of active pickups get in the way of the management concept.

The Seymour Duncan HyperSwitch is equipped with a Bluetooth module, which is switched on by switching back and forth between positions 1 and 5 of the switch several times. The connection can then be established to the personal mobile device, which, as expected, must have the associated Seymour Duncan app on it. The maximum variety of sounds can be found when as many pickups as possible are equipped with as many separate winding guides as possible, because this is the only way the switch can demonstrate its full performance. To put it bluntly, the 5-way switch still allows "only" a number of 5 different sounds, but these can be freely distributed across the 5 different switching positions. This means that constellations can be selected that couldn't be more different, but are still only one switching position further.

A big advantage of the Seymour Duncan HyperSwitch is that no solder is needed when installing the switch and pickups. All pickup wires are only plugged into the switch at the respective connections and then locked with a small screw. Very practical! Seymour Duncan gives a 4-year guarantee on the HyperSwitch, which speaks for a great deal of confidence in the workmanship of the switch made in China.

Installing the Seymour Duncan HyperSwitch

For all instruments that are delivered with a classic 5-way switch, such as Strats, many Ibanez models, etc., installation is quite simple. Remove the strings, loosen the pickguard, get the colored markings for the wires from the respective manufacturer's website and you can start with the new wiring. To separate the wires from the old 5-way switch, you can unsolder them or simply cut them off. The tone control and the volume control are also included in the new wiring.

The switch offers 4 wiring points per pickup, meaning 12 input points on one side and 6 input points on the other side for the input area of ​​the volume and tone controls. 2 inputs are already occupied by the 9V clip. If the cavity in the switch compartment is not large enough for the shape of the Seymour Duncan HyperSwitch, you can also "flip" the switch in its switch position so that you swap the order of the switch positions 1 - 5. This can be set accordingly in the Bluetooth app on the mobile device.

Wiring the Seymour Duncan HyperSwitch is a bit fiddly due to the very small screws, but can be done relatively easily thanks to the screwdriver provided. I recommend taking photos of the old wiring before starting any work so that you can use the original wiring as a reference for the area of ​​application if necessary. In addition to the screwdriver, 2 fastening screws and the plastic cap of the switch are also included.

The Bluetooth app

After downloading the app, you connect to the switch using the usual Bluetooth principle. Make sure that the 9V battery still has enough voltage; it should not have less than 65% remaining capacity. The app itself has a very nicely designed interface where you can activate your personal pickup constellation by tapping.

First of all, you should create an account on the Seymour Duncan website. When you first start using the app, there is a short overview of the individual features of the app, which also gives a little help with the individual menu items. The first suggestion then appears: a typical Strat circuit with 3 single coil pickups, which you can then adjust as you wish via the menu. Each pickup position can be selected separately, with Seymour Duncan offering pretty much every pickup from single coils, Strat size humbuckers, full size humbuckers to stacked pickups and P-rails. You can also mute a pickup position if required and thus set up a kill switch position.

Once you have made your pickup selection, you still need to configure the tone control, which is also done via a submenu. This is also where you set whether the instrument has one or two tone controls. To extend the battery life, you can set the activity time of the HyperSwitch in the app. It is set to 3 hours by default, but can be extended accordingly for longer shows or theater performances, for example. Of course, several pickup constellations can be saved with individual names and loaded accordingly depending on the area of ​​application. You can save both the individual switch position and the bundle of all 5 switch positions as a preset.

The Seymour Duncan HyperSwitch in practice

As soon as you have established the connection between the instrument and the app and the basic setup of the app has been completed, you can start programming your sets. The selected pickup lights up and can then be selected and saved according to the coil options. This is absolutely intuitive and can then be checked directly on the amp for its sound shaping. You can click on the respective coils of the pickups on the app or you can use the name of the respective circuit underneath. The selection options, especially with three humbuckers with separate coil tapping, are immense and you can easily run the risk of getting lost in the finer details. But that's not all, you can use the tone control to intervene in the sound again and save it. The tone control can be switched off, operated normally or operated with a 0.27 capacitor.

The variety of sounds offered by the Seymour Duncan HyperSwitch is truly enormous, but you should always keep in mind that the full range of sound variations decreases with increasing gain factor, so that in the high gain range the majority of the sound difference is ironed out. The full range of sound variations can ultimately only be perceived in the clean and subtle crunch range, and then loses some of its subtlety with each gain level. This fact is not due to the concept of the Seymour Duncan HyperSwitch, but rather a simple physical fact.

Nevertheless, the concept is convincing across the board and enables an incredible variety of sounds with minimal modification work, especially when you consider the massive woodwork that would be necessary for a purely analog circuit with such variation options.

Conclusion

With the Seymour Duncan HyperSwitch, the American manufacturer has a very good tool in its portfolio when it comes to maximum sound variety with minimal modification work. The retrofittable 5-way switch, in conjunction with the appropriate Bluetooth app, enables an incredible variety of sounds, especially if you have equipped your instrument with 3 humbuckers.

Anyone who mainly plays with little gain will appreciate the extremely large selection of sounds, especially since you can use a corresponding preset database to adjust the respective pickup configuration to the desired band / project.

### The History of Seymour Duncan Pickups

Seymour Duncan Pickups, a name synonymous with high-quality guitar pickups, has a rich history that reflects both innovation and a deep passion for music. The company's journey from its humble beginnings to becoming a major player in the music industry is a testament to the dedication and craftsmanship of its founder, Seymour W. Duncan, and the team that joined him on this journey.

#### Early Beginnings

The story of Seymour Duncan Pickups begins in the 1960s, a transformative era for rock and roll. Seymour W. Duncan, born in New Jersey in 1951, exhibited an early interest in music and electronics. As a young guitarist, he was particularly fascinated by the sounds produced by electric guitars and the pickups that amplified those sounds. This curiosity led him to experiment with winding his own pickups, a process that involves wrapping wire around a magnetic core to create the coils that capture the vibrations of guitar strings.

During these formative years, Duncan would spend countless hours dissecting pickups, learning their intricacies, and attempting to improve upon existing designs. His dedication to understanding the mechanics of pickups was driven by a desire to replicate the tones of his musical heroes, such as Jimi Hendrix, Jeff Beck, and Eric Clapton.

TEST: Sennheiser XSW-D

 Guitarists and bassists who want to play with a transmitter are familiar with the problem. Apart from the differences in sound, there is sometimes the problem, especially with 19-inch solutions, that the transmitted signal that arrives in the rack has to be fed back to the floorboard via cable, especially since this is where the tuner is usually located. With the Sennheiser XSW-D Pedalboard Set, Sennheiser has a combination of radio link and tuner in its luggage, which at least makes cable routing obsolete.

The design of the Sennheiser XSW-D Pedalboard Set

The Sennheiser XSW-D Pedalboard Set is a member of the XS Wireless family, which also includes models from the microphone and camera sector. They all have the function of wireless signal transmission in common. The guitarist version comes with a tuner / receiver floor pedal combination, a plug-in transmitter, 2 cables and a multi-voltage power supply, which also offers worldwide use thanks to the power adapter supplied.

The transmitter, which can either be plugged directly into the guitar's jack socket or attached to the guitar strap as a body pack using the extension provided, can be operated with one hand, provided you can remember the different color schemes of the built-in LED and push button. The battery life is specified as up to 5 hours, which corresponds to about 2 extended shows with your own songs or a cover band show with 4 - 5 sets.

Sennheiser promises a range of up to 75 meters, but this refers to an open field with no obstacles. My experience tells me that for practical use you should assume half the manufacturer's value, which in this case would still cover the largest open air stages in the country, especially since you should keep in mind that the receiver is located at the front edge of the stage due to the pedal design, which adds a few meters to the range.

The Sennheiser XSW-D Pedalboard Set also operates on 2.4 GHz and therefore has to deal with the big problems of thousands of cell phones in the audience area and, even worse, the sometimes very strong radiation from the stage radio, which is always used on large stages and, depending on the orientation, simply "knocks out" the signal. In order to be able to judge this, I will use the transmitter at several large festivals that I am attending in the next few weeks, including a tour in Japan. If there are any unexpected failures, I will mention them in an addendum. In general, however, I believe that the Sennheiser trademark, with a retail price of just under 400 euros, offers a more stable option than the various plug-and-play solutions in the almost three-digit range.

The play of colors of the Sennheiser XSW-D Pedalboard Set

The entire appearance of the Sennheiser XSW-D Pedalboard Set is designed for simple yet elegant handling, which should visually get by with as little information as possible. Therefore, the LED installed on the transmitter uses the following color play to provide an easily understandable information policy:

Briefly press the LED button for max. 1 second = switch on the transmitter - LED lights up green

Press the LED button again for max. 1 second = mute the transmitter - LED lights up yellow

Press the LED button for min. 3 seconds = switch off the transmitter

After switching on the transmitter, the LED briefly lights up green = battery power over 75%

After switching on the transmitter, the LED briefly lights up yellow = battery power between 5% - 75%

After switching on the transmitter, the LED briefly lights up red = battery power under 5%

Alternating red and green flashing = the range is exhausted

Charge level solid green = battery fully charged

Charge level flashing green = battery over 75% charged

Charge level flashing yellow = battery between 5% - 75% charged

Charge level flashing red = battery under 5% charged

The Floor pedal of the Sennheiser XSW-D Pedalboard Set

The floor pedal of the Sennheiser XSW-D Pedalboard Set contains not only the receiver but also a chromatic tuner, which does not have the usual red and green LEDs, but rather a monochrome, fairly large display. This has the advantage that the letters and symbols can be seen much better than with LEDs, especially in direct sunlight. Anyone who has ever played on an open-air stage at midday in direct sunlight knows what I'm talking about.

The pedal itself is very solid and should be able to withstand any tough stage use. If it is used without a pedal board, two rubber pads on the underside of the housing ensure the necessary grip on smooth surfaces. For floorboard use, Sennheiser also takes the really tough route if necessary. The scope of delivery includes a drilling template with which you can drill holes in your board to secure the pedal with the appropriate screws. If the Velcro / cable tie solution does not seem stable enough, here is the solution.

On the front side, in addition to the jack output for the other pedals or the amp, there is also the input for the included power supply and a 5V USB-C output for charging the transmitter. The transmitter can also be charged using a standard mobile phone power supply. It is only advisable to make sure that it is USB-C, as the increasingly popular plug variant has not yet arrived in all electronics stores.

The transmitter of the Sennheiser XSW-D pedalboard set

The transmitter of the Sennheiser XSW-D pedalboard set has a foldable jack plug that can be bent depending on the guitar model and personal preference. While this works very well with Strat-type models, it is a little more problematic with the LP-style side solution. Due to the long housing shape, the lateral torque is quite strong when used at an angle and sometimes twists the plug. If you don't move around much, you can of course also insert the plug straight down. In general, however, I would recommend backpack operation, which is also offered.

The Sennheiser XSW-D pedalboard set in practice

Switch on, pair, done. In fact, it is as easy as it sounds. The transmitter and receiver found each other within 2 seconds, which is really extremely fast. Let's start with the sound. In order not to start the cable discussion for the umpteenth time, here is a general statement. Yes, a transmitter sounds different to a cable. Yes, every transmitter, regardless of its design and retail price, sounds different to a cable. No, a transmitter does not sound worse, just different!

It is more than just tiring to read the forums about the eternal pros and cons of transmitters and cables. The fact is that a cable represents the most stable signal transmission and is a decisive criterion in the overall sound, especially with passive, high-impedance pickups. But it is also a fact that an entertaining stage presence suffers massively as a result. Anyone who only moves in the beer mat area should stay away from a transmitter. On the other hand, anyone who covers longer distances on stage and would like to entertain the audience with artistic interludes will not be able to avoid a transmitter.

In terms of sound, the Sennheiser XSW-D pedalboard set differs from a 6 meter (Cordial) cable in that the sound is a touch louder, a little more pronounced in the highs and a little more compressed. Especially for high gain guitars, these are all attributes that you would otherwise get from the amplifier and any floor pedals you might use. I personally really liked the overall tighter sound, especially since a latency of around 4 ms is no longer noticeable when playing.

The product had to pass a tough range test. I placed the product in the recording room of my recording studio, which was built like a room-within-a-room, closed both doors and looked at how far the signal could now reach. The device, which was shielded in this way, was still able to send the signal about 30 meters through the walls before it started to drop out. A really very good value when you consider that other products of this type gave up the ghost when the two doors were closed. Otherwise, the system generally leaves an excellent impression in terms of workmanship, practical use and performance data.

Conclusion

With the Sennheiser XSW-D Pedalboard Set, one of the big German flagship companies has launched an excellent product that shines with very good workmanship, practical implementation and very good performance data on a broad level. Anyone looking for a combination of tuner and transmitter system for string instruments should definitely try out this product.

Additional Informations:

The story of Sennheiser, a name synonymous with high-quality audio equipment, began in the wake of World War II. In June 1945, Dr. Fritz Sennheiser, along with seven fellow engineers from the University of Hannover, founded the Laboratorium Wennebostel, known as "Lab W," in a farmhouse in Wennebostel, Germany. This small team, with limited resources but boundless determination, embarked on a journey that would transform the audio industry.

Initially, Lab W focused on producing measuring devices, with its first product being a voltmeter. However, the shift towards audio equipment began shortly thereafter. The company’s early forays into audio technology laid the foundation for its future success. By 1947, Lab W had developed its first microphone, the MD 2, a significant step towards establishing its reputation in the field of acoustics.

### The Transition to Sennheiser Electronic

TEST: Sennheiser EW 300

 Even though I have experienced it countless times in my career as a sound engineer and musician, it always surprises me how products that were only available to a very elite circle of top 10 artists a few years ago due to their price are now treated like bread and butter items.

This product category undoubtedly includes the wireless system, which most people will know better by its street name "in-ear monitoring". While the first practical wireless transmitters for guitar and bass were already a revolution, the same system enabled a singer, who could walk through the entire stadium of an open-air concert with the same monitor sound every time, using a wireless microphone, to make the ultimate quantum leap in performance.

Prices in the five-figure range with limited radio frequencies, dropouts every minute thanks to reinforced concrete and a battery life of a maximum of 70 minutes were not uncommon at the time, and yet the products were worshipped like a holy grail. In-ear = superstar, basta!

How practical, on the other hand, is a product like the Sennheiser EW 300 IEM today, which offers many times more operational reliability and flexibility at a price of a tenth of the price at the time.

One should not forget that said radio links are not only used in the music sector, but also, as is often forgotten, in the audio/video sector, or reporter work, whereby the requirements vary according to the area of ​​application.

While the music sector primarily places value on sound and operational reliability, in the video sector, interference resistance and in the reporter sector, signal stability even under adverse conditions are of great importance.

Construction:

The scope of delivery of the EW 300 radio link consists of a stereo receiver, stereo transmitter, a telescopic antenna, power supply, a set of earphones, two batteries for the transmitter and an instruction manual, packed in a sturdy foam case.

The EW 300 has five frequency ranges in the UHF band, each with 1440 transmit/receive frequencies, available for signal transmission. These ranges are divided as follows:

Range A: 518 - 554 MHz
Range B: 626 - 662 MHz
Range C: 740 - 776 MHz
Range D: 786 - 822 MHz
Range E: 830 - 866 MHz

The small EK 300 IEM G2 transmitter unit has a moderate weight of 170 grams, including the two Mignon AA batteries it requires for operation. Depending on the volume used, according to the manufacturer, one set of batteries should provide between 6 - 10 hours of operation.

The transmitter can also be operated with a battery pack, whereby the transmitter can be inserted directly into an external Sennheiser charger (L 2015) via two external contacts. The charger is not included in the scope of delivery and must be purchased separately.

A small but easy-to-read display provides all current information such as channel selection, transmission frequency, radio level, audio level, muting, pilot tone evaluation and locking of the device. A small, very flexible antenna with a plastic coating is used for signal transmission.

The receiver counterpart weighs a hefty 1100 grams due to its solid sheet steel coating. The device is supplied in half 19" size, 1 HE, and can be expanded to a full 19" width using the adapter supplied. An antenna extension cable is supplied for this so that the antennas can now be screwed onto the front of the extension. A small but very useful detail!

The receiver has 2 symmetrical XLR females on the back for signal feed-in, the data port is only designed for service purposes. The connections for the antenna and the strain-relieved connection for the external power supply are also located here. The EW 300 can handle anything between 10.5 - 16 volts at 300mA.

There is an additional headphone connection on the front for monitoring purposes, the volume of which can be adjusted using a volume control. The on/off switch is also located here, as well as two rocker switches and a set switch. The easy-to-read display is located in the middle of the panel and provides information about the channel bank, channel number, frequency range and audio level parameters.

In order to increase the signal-to-noise ratio for wireless sound transmission, the transmitter and receiver are equipped with the patented, non-switchable HDX noise reduction system, a broadband compander that compresses the audio level on the transmitter side in a db 2:1 ratio and expands it again on the receiver side.

The earphones supplied have various plastic attachments to accommodate different sized ear canals.

In practice:

After the power supply has been plugged in, a red ring around the on/off switch informs us that the device is being supplied with power. After activation, the EW 300 automatically searches for a free frequency on which it can transmit the signal. Activation works without problems on the first attempt.

The transmitter can be attached to your trousers or belt in a few simple steps, where it stays during the entire test without wobbling or even slipping.

I would describe the sound of the earphones as good with a light to medium high-mid emphasis. Personally, I find the basic sound a bit too "biting", but this is a purely subjective criterion and does not affect the evaluation.

In order to make it really difficult for the EW 300 in terms of its operational reliability, it was allowed to demonstrate its transmission capabilities from the basement of my house. The facts: 1960s construction, very high steel content in the reinforced concrete ceilings and blessed with a "Faraday cage effect" up to the stand-up collar. You can't make it more difficult for a transmitter.

None of my Macs' Airport Stations made it across more than one ceiling here, and with the second ceiling, any detection of even the smallest field strength is a pure stroke of luck. Whatever comes through here has outstanding transmission power!

And off we go. The fed-in signal is at full deflection and I start walking. First solid wall, still at full deflection. The first floor, the first reinforced concrete ceiling, one beam less, full sound without any dips. The second reinforced concrete ceiling, one more beam less, still no problems.

Now I want to know! Two reinforced concrete ceilings plus a walk outside. After 20 meters the first dropouts in the stereo image, after 30 meters the first distortions in the earphones, after 40 meters it's time to call it a day!

But oops! Now that's what I call a transmission! The values ​​given by the manufacturer of up to 150 meters with direct line of sight do not seem exaggerated at all. Anyone who can master this hellish structure in my basement has nothing to fear!

Conclusion:

All respect, Sennheiser has pulled off a remarkable feat with the EW 300! The device is excellently manufactured, extremely easy to use and impresses with its outstanding transmission and reception performance.

A very good product, Made In Germany, which will not disappoint its users!

Throughout the 1960s and 1970s, Sennheiser continued to refine its wireless technology. The introduction of the SK 50 in 1972 marked another significant milestone. The SK 50 was one of the first wireless systems to use frequency modulation (FM), which offered improved sound quality and reduced interference compared to earlier amplitude modulation (AM) systems.

The SK 50 also introduced the concept of diversity reception, which used two antennas and two receivers to minimize signal dropouts and ensure a more stable transmission. This technology became a standard feature in many of Sennheiser's subsequent wireless systems, significantly enhancing their reliability and performance.

### The Evolution of UHF Technology: Entering a New Era

The 1980s saw a major shift in wireless technology with the advent of ultra-high frequency (UHF) systems. UHF offered several advantages over VHF, including a greater range of available frequencies and improved resistance to interference. Recognizing the potential of UHF, Sennheiser introduced its first UHF wireless system, the SK 2012, in 1982.

The SK 2012 represented a significant leap forward in terms of both performance and versatility. It was designed to operate in the UHF spectrum, which allowed for more channels to be used simultaneously without interference. This made it ideal for large-scale events and complex audio setups where multiple wireless systems needed to operate in close proximity.

TEST: Sendy Audio Aiva

 When I first heard the name Sendy Audio, I had to admit to my shame that I had never heard this name before. However, a little research made me aware that the Chinese manufacturer appears to be an established manufacturer in the HiFi sector that now wants to expand its presence into the pro studio area. For testing, we have the Sendy Audio Aiva, which, with a retail price of €649, is in the upper price range and faces plenty of competition from established manufacturers such as Beyerdynamic, AKG, Fostex and many others. Let's see what the Aiva has to offer in terms of setting features.

The packaging and accessories of the Sendy Audio Aiva

Anyone like me who has around 15 headphones to store in their studio is always happy to have packaging that offers stacking as a third storage option in addition to the usual stuffing in drawers or sometimes helplessly hanging them on microphone stands. Here, Sendy takes the pole position by adding a durable hard case with a coarsely toothed zipper plus 4 plastic feet for upright positioning to the headphones. Unfortunately, a few threads came loose from the zipper seams after a short time, but these could be cut off.

What is an absolute no-go, however, is the repeated use of real leather within the product. The entire cover of the hard case and, as it later turned out, the carrying strap and the ear pads were made from so-called high-protein leather, which is no longer ethically sustainable these days. There is a huge amount of synthetic leather, such as that used in all Apple accessories, which is even superior to the skin of dead animals in several wearing and care aspects and excludes the suffering involved in obtaining real leather.

In addition to the actual headphones, there is also a small fabric bag inside in which the connecting cable and an adapter are housed. This is where you come across the first unusual approach that the Sendy Audio Aiva has to offer. The copper-colored, double-sided and pluggable headphone cable is supplied in the basic version with the extremely rare 4.4 mm Pentaconn plug. Well, it may be that the acceptance of this plug may increase in the future and a short adapter cable is also included for regular stereo mini jack operation, but wait, isn't there something missing? It's hard to believe, but it's actually true that anyone who wants to use these headphones with the standard 6.3 mm jack output, which is used in 99.9% of all listening situations in the studio, has to buy an additional adapter. A decision that I absolutely cannot understand.

Well, maybe the manufacturer is focusing more on the classic mobile device as a sound source, which would also explain the low impedance of just 32 ohms, but here too the adapter solution is not convincing. The Pentaconn mini jack adapter is very solid, but also so heavy that it puts excessive strain on a headphone jack when in use, not to mention a lightning to 3.5 mm adapter. For me personally, this is a very questionable and completely impractical solution in every respect.

The design of the headphones

Let's turn to the headphones. As expected, the real wood shells are the big eye-catchers, which are made from zebra wood (zebrano), a protected tropical wood grown in West Africa. The foam pads are cut asymmetrically and try to compensate for the shape of the face, which normally gets slimmer towards the bottom, to ensure even pressure. In my case, this worked very well. The unusual hinge solution for adjusting the head width was also impressive in detail, although a little stiff.

What worried me personally, however, was the very heavy weight of the headphones in my test model, which weighed 460 grams without a cable and 540 grams with a cable, which caused several problems. Firstly, I found the latent pressure on the neck area to be quite tiring, and secondly, the weight of the headphones meant that when I turned my head quickly, they exerted a lot of centrifugal force, which made them unstable on my head at least. However, everyone should decide for themselves whether they can cope with this weight.

For people with small heads, there may be problems with the pressure of the headphones. For my head shape, the smallest setting was just enough to give the headphones the necessary stability; unfortunately, a tighter setting was not possible. Although you can open the connection of the strap using a Torx screwdriver, it is unfortunately not possible to increase the tension due to the widened shape of the strap.

The technical data of the Sendy Audio Aiva

The first setting feature of the Sendy Audio Aiva is the planar magnetic drivers, which are said to be very insensitive to any kind of sound distortion due to their design (very thin film between 2 magnets) and also impress with a very fast response and an extremely neutral sound. According to the data sheet, the headphones have a frequency response of 5 - 50,000 Hz, which is far above what the human ear can perceive in both the bass and treble ranges. The extent to which this approach makes sense is controversially discussed by several experts, so I don't want to open up this can of worms in this test report. The headphones are designed to be open, with the sound pressure reaching a rather low value of 96 dB.

The sound of the Sendy Audio Aiva

Connected to an iPhone X, the headphones seem relatively quiet at first glance despite their comparatively low impedance. In order to get a decent level, I had to use the Lightning adapter to turn up the volume to the upper quarter. When using a high-quality headphone amplifier, in my case an SPL Phonitor, this point was of course irrelevant. In terms of sound, however, the headphones are convincing in several respects. Firstly, the headphones sound very "calm" without sounding too analytical. The general sound impression is very balanced and immediately leaves a pleasant basic mood. The detail is very good and, even with heavily mastered material, still provides enough instrumental differentiation, which is often lacking, especially with tonally questionable material. A very good example is the hi-hat or the entire cymbal area of ​​a drum set, which in many heavy productions only exists on paper, but here it can sometimes hold its own very well in the sound.

The often problematic mid-range is also convincing. In several productions, both in the reference range and in albums I produced myself, the guitars, whether in standard or drop tuning down to baritone tuning, held their own and were reproduced with accentuation. The vocals were also drawn with sufficient detail without the corresponding sibilants being resolved too finely.

In terms of tone, the Sendy Audio Aiva brings out the typical planar magnetic sound, i.e. the headphones are extremely quick to respond, bring out the bass range discreetly but tightly and color the highs very slightly with a touch of compression. The ultra-high range is somewhat reduced than with other headphones, but this does not detract from the good overall sound. In contrast to its limited wearing comfort, in my opinion, the long-term acoustic use offers no reason for criticism. The sound is still pleasant even after a long studio session and enables fatigue-free work.

In general, the Sendy Audio Aiva makes a variety of signals sound "better" than is sometimes the case. This headphone is very suitable for "feeling good", but you should definitely listen to it again and again on various "challenging" monitors to be on the safe side.

Conclusion

The Sendy Audio Aiva leaves a polarizing impression in its overall impression. In terms of sound, the planar magnetic headphones impress with a very balanced and cleanly accentuated sound, which is very relaxed with plenty of headroom and is a very good tool for longer sessions.

On the other hand, it scares users off with its high weight, impractical cabling including a lack of adapter accessories, limited wearing comfort with a small head circumference and the use of ethically questionable materials.

If the Chinese manufacturer were to eliminate the negative points, which are all very easy to fix, you would be dealing with a top-class headphone that only sounds excellent. As it is at the moment, everyone has to decide for themselves whether to give the Sendy Audio Aiva a chance.
