"This is the ARP AVATAR. It is basically a Arp Odessy without a keyboard controller. It was intended to be used with the guitar MIDI controller pickup that I no longer have. my tech tells me that the Roland midi guitars or a Roland-style or any hex pickup will work. I used this with a Kenton box (midi to cv converter) which turned it into a tabletop synth module. I just had all the sliders replaced and it's pretty satisfying to play with.

It is from 1977 so it's not brand new. I just sent it to my tech to make sure it's all working and we decided to change all the sliders out. When I bought this 15 years ago it came in a road case that was deteriorated and left marks on the wood panels on the sides as seen in the pics. I did clean them up a little. If you are someone who is handy I am sure you could clean these up to look like new if you are inspired to do so."

Go beyond Eurorack! Modular synth + Pedal & rack FX & instrument input // DPW Design Pedal Interface

video upload by DivKid

"I've always enjoyed integrating other gear beyond the realms of the Eurorack case. Synths and FX, guitar into modular, rack gear processing beats ... it's a great thing to explore, to find unique tones and new sounds.

The new Pedal Interface from DPW Design is a 4HP stereo or dual mono pedal/instrument input and output module. While it couldn't be simpler on the interface this was designed to address two issues and to improve working with the varied signals. DPW made sure to properly impedance balance so you're not sucking out the tone and brilliance in the signal and sought to address transient handling and add a tube inspired gain structure above the clean gain structure for adding tube like compression and saturation FX ... something we exploit for great distortion in the video!"

P1, Pedal I/O

The P1 is a dual channel pedal interface. It can be used for pedal or line level in and out or as a guitar or bass input as the pedal in is a high-Z input that will not suck the life out of the tone of your instrument as low impedance inputs can do.

The module is designed to have more than 100kHz bandwidth in both directions to give you a very clean interface with in and out impedance to work well with pedals.

The two halves of the module are independent. You can use it as a dual mono or as a stereo interface.

Eurorack to pedal level is attenuating -18dB and pedal to Eurorack level is amplifying 18dB.

There is soft controlled symmetrical clipping in both directions through the module so if you are driving the inputs hard it will not sound harsh. You can use this as a creative effect.

The unit is AC coupled to be able to isolate your Eurorack from whatever you connect on the pedal side.

Playing Synthesizers...with a Guitar?! Jamstik Visits the Perfect Circuit Showroom

video upload by Perfect Circuit

"Jamstik makes a line of wildly fun guitars—but hey, you might be wondering...why does a synth shop like Perfect Circuit give a heck about a guitar? Well, for one, all instruments are beautiful—and two, Jamstik makes MIDI GUITARS. They function perfectly well as standard electric guitars, but they also use proprietary technology to translate your guitar playing into MIDI data that synthesizers understand.

Not only that, they use a clever mapping of detected audio data in order to generate MPE (MIDI Polyphonic Expression) data...making them a nuanced and quite powerful and expressive means of interfacing with MPE-capable synthesizers.

Jamstik recently came by our Burbank, CA showroom to see what they could do plugging their guitars into our synthesizers. With the expert guidance of our very own Jacob Johnson, they narrowed in on the Groove Synthesis 3rd Wave, Roland Juno X, and, of course, a Eurorack modular system featuring Tiptop Audio's new ART-equipped modules.

Roland G-505 Guitar Synthesizer Controller, GR-300 Polyphonic Guitar Synth

via this listing

"Up for sale, a 1980s Roland G-505 Guitar Synthesizer Controller and GR-300 Polyphonic Guitar Synthesizer [SN 090427] in 100% original condition and in perfect working order, complete with the original 24-pin cable. First introduced in 1980 as a follow-up to the GR-500, the GR-300 is perhaps best known for its usage by Pat Metheny; produced at the venerable Fujigen factory in Japan, this versatile guitar synth can deliver a huge range of decidedly unique sounds, with a hexaphonic fuzz circuit, VCO synth, and combinations of the two. This GR-300 comes complete with the G-505 Guitar Controller, taking its design cues from a Strat with a sleek ash body, one-piece maple neck, and a trio of single coil pickups alongside the synth pickup.

The G-505 Guitar Controller guitar has plenty of natural sparkle and shimmer, and the Roland PU-134S pickups deliver a bevy of Strat-style tonalities via the five-way selector switch. Weighing 8lbs 12oz, the G-505 has been professionally setup here at Mike & Mike’s Guitar Bar with 10-46 strings, low action, and spot-on intonation.

The maple neck has a slender C-shaped profile carve with good shoulders, gaining appreciably more heft and roundness in the upper registers, measuring .810” deep at the 1st fret and 1.015” at the 12th. The fretboard exhibits light finger wear through the gloss, and the slender fretwire ostensibly benefits from a level and crown in this guitar’s lifetime, showing virtually no wear. This Roland plays cleanly up the 25 1/2“ scale with a straight neck and a responsive, optimally-adjusted truss rod, and the nut measures 1.650” (42mm) in width. The headstock features a bullet truss rod nut and gold “GR” logo, and the Gotoh tuning machines function reliably. The back of the headstock retains the silver foil serialized sticker.

The electronics on the guitar controller are untouched, with a control scheme including Master Volume, Guitar Tone, Guitar/EG Balance (Blend), VCF Cutoff Frequency, VCR Resonance, and LFO (Vibrato) Depth knobs. Additionally, the three-position Mode toggle enables on-the-fly switches between Hexaphonic Fuzz only (Mode 1), Fuzz and VCO synth tandem (Mode 2) and Synth only (mode 3). The controls are capped by the original sextet of knobs with ridged grips for easy adjustments, and the three-ply white pickguard rounds out the plastics.

Cosmetic wear on the gloss Metallic Blue finish includes a number of nicks and dings on the body as a whole, most prominent along the lower bout perimeter, with some finish chipping adjacent to the output jacks, and some very subtle texturing in the finish on the top. The neck profile retains its smooth gloss, with a handful of shallow marks that have no impact on playability.

Roland GS-500 Synthesizer Guitar *AND* GR-500 Synth Module SN 661034

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"This joint venture instrument between Roland and Ibanez is paired with the Roland GR-500 module. It was used by a multitude of artists, ranging from Neal Schon of Journey to Jeff Baxter of the Doobie Brothers and was responsible for creating some of the wildest synth guitar sounds of the late 70s and 80s.

The guitar features a hexaphonic pickup that tracks the pitch of each individual string with high accuracy, as well as a traditional humbucker pickup for producing standard guitar tones. The signal is sent through the guitar’s 24 pin output to the synth module where it can be manipulated using a multitude of VCOs VCAs filters, and effects. One of the most unique elements of the guitar is the infinite sustainer system built into the guitar. Similar to how E-bow’s work, this instrument can keep the strings vibrating as long as the player wishes.

This guitar is in excellent condition. It has only a handful of small chips/dents on the top (pictured) and the fretwear is nonexistent. Its electronics have been cleaned, the fretboard conditioned, and setup to play well at low action. The GR-500 Module has been well cared for, and is in excellent shape. Bring your guitar music to the next level with the GS and GR 500s today!

"In this video, my guitar is plugged into a USB audio interface, and then directly injected into Anukari. No other effects (i.e. cabs, amps) are in use other than a little bit of compression. This is a fully wet signal with no dry mixed in, so everything you are hearing is from Anukari."

How to use "Sooper Looper" on Zynthian for guitar looping

"Here's the SooperLooper #looperpedal module built into the #Zynthian #raspberrypi #diysynth , used with a #guitar. The looper is treated as an effect, so you can include it in any part of your effects chain, routing (as shown in this video) a compressor into an amp model into the looper into a delay and reverb. As always, don't expect great guitar playing in this video. This is a tech demo first and foremost. Video doesn't need an index this time. #poorguitarplayingpimpedwithepicreverb"

Showcasing the String Armonica: Live Demo of a New Electro-Acoustic Synthesizer

video upload by The Sound Stone

"We are thrilled to showcase our new prototype: The String Armonica. This new electro-acoustic synthesizer employs electromagnets to resonate twelve distinct strings. Using the power of harmonic resonance, we've managed to design it to play up to 48 notes of full polyphony using a MIDI controller. All the sounds that this instrument produces originate solely from the vibrations of the strings themselves. Nested within the body of the instrument lies a a polyphonic synthesizer, which outputs notes that resonate the strings and they're octave harmonics.

The String Armonica works differently than how a guitar sustainer works. In a sustainer (Sound Stone, Ebow, etc), it will resonate a string regardless of its tuning. In order for the String Armonica to correctly work, the strings must be tuned so that they match the resonant frequency of the internal synthesizer. By adjusting the tuning pegs, you're able to 'voice' the loudness of each octave and can make certain octaves louder than others or of equal volume.

When you listen through headphones, the stereophonic output becomes evident as one set of strings is panned to the left and another to the right, creating a rich, immersive experience. However, a monophonic option is available as well.

The name of the instrument, 'The String Armonica,' pays homage to the rare Glass Armonica, an exquisite crystal glass instrument invented by Benjamin Franklin. The resemblance in the sound produced by our instrument to that of a Glass Armonica is very similar which is why we thought of this name.

In our improvisation demonstration, we explore the instrument's potential by adjusting the volume with an expression pedal and using the mod wheel of the MIDI controller to generate a staccato tremolo effect.

It's important to note that this is a prototype. In its current state, it may appear a bit rough around the edges due to several adjustments and changes we've made along the way. The final manufactured version will be significantly more refined and less crude.

For those interested in owning one of these innovative instruments, we encourage you to add your name and email to our pre-order list. Once we are ready to commence manufacturing, we will send you additional information and a purchase link.

"This is an Oberheim SEM on the inside, originally marketed by 360 systems for the guitar market. This one was MODIFIED for CV Gate control (it’s not set up for use with guitar).

This unit was meticulously serviced over 10 hours to work like new again, no typical lies or excuses, making this unit better and more valuable than others you may find. Power supply recapped. Molex connector terminals replaced. VCO VCF VCA recalibrated. All pots and switches properly cleaned and lubed. Modified (see below). Audio input added. Cleaned inside and out.

Note: The latches that hold the lid in place are broken and we didn't have a source for replacements.

This 360 Systems Guitar Synth came to us without a guitar pickup (they're usually broken, when they're present), so we had our tech modify it for use with CV and gate from any compatible CV gate devices (including most if not all available midi to CV converters). He also modified it so there's full control over the VCA envelope generator, adding 2 potentiometers for the 2 envelope control that are missing from the stock Spectre in the place of 2 1/4" jacks that aren't needed when using it without a guitar. Since this unit's not set up for use with a guitar, the left side controls have no effect (string related stuff, octave select and transpose settings). We also need to make it clear that since we couldn't test the guitar related stuff, we have no idea whether the guitar section would work if you had a pickup, so are selling this unit strictly as is. If you plan on trying to use it with a guitar and pickup, please realize this. All other controls for the synth section are working perfectly and play beautifully via the CV and gate jacks."
