Simmons Clap Trap


This machine needs no introduction. Everyone who knows “clap machine” knows that the “Famous Clap Trap by Simmons is the best clap trap ever built. You can trigger it, play it, trigger it from a microphone, use it in the studio and more.

I used it on my snare using a microphone on my acoustic set. People would ask me after a gig all the time, “man what is that you’re using on your snare drum, it’s slammin, I told them it was the Simmons claptrap and they would reply, “that is the fattest clap I’ve ever heard. You will be amazed. This is a hard to find…!!!!! Hate to let it go… but I Gotta. It is very clean no scratches all knobs and buttons in tact works great!!!!” Click here to search for synths on eBay

Oberheim Matrix 6R

“Oberheim Matrix 6R rack mount synth.

A matrix 6 in a rack mount!! Good condition.

Amazing sounds. Huge-even.

Typical rack wear, but it has been well maintained.

the power supply was recapped a few years ago.

we did it just to be safe.

This works perfectly, operating system is 2.1.3

I think I have a file with stock sounds that I can send or burn to a disc.

I do have many of the stock sounds slightly altered to use a midi cc controller for cutoff and resonance.

What this means is that many of the sounds currently loaded don’t really make much noise until you give your midi knobs a little tweak.” Click here to search for synths on eBay

“Italian made GRP A-4 Analog Synthesizer

Offers 3 full-feature oscillators, plus 2 discrete LFO’s. S&H, Noise, Mixers, 2 ADSR, 16-Step sequencer, A-440 generator. 12dB State variable filter and 24dB Low pass filters, Glide, Auto-pan, accepts external signals, Stereo Headphone TRS jack. CV/gates in and out. MIDI and USB in rear. Complex routing features: provides virtually the same flexibility of a modular without the need for patching. The A-4 is single-voice, and does not store patches.

Audiophile timbral quality. Truly holds its own with ANY other synth. One of the most beautiful synths ever made.

The reviews say the A-4 blows away the Moog Voyager XL. The GRP has much more power and flexibility and the fidelity is superior to the Voyager. If you are looking for a Model-D sound, then buy a Model D, cause even Moog’s re-issue doesn’t sound like a D to many. The GRP is not a Moog clone.

This is one HELL-of-a synthesizer, semi-rare. Will retain its value; so buy it, use it, then sell it for what you paid for it.

The cabinet appears to be a walnut veneer. Other than that, the unit looks brand-new. I am third owner. None were smokers, home studio only, never live gigged, super low hours. I only had it a week before urgent medical bills appeared from my daughters ear surgery. :(“ Click here to search for synths on eBay

EDP Wasp

“A rare Electronic Dream Plant Wasp Synthesizer, serial # 001133, in working condition. Purchased from a US EBay seller in March 2016.

The original listing didn’t show what appear to be holders for a strap attached at the front of the base – to my knowledge no Wasps were produced with these but it appears to be a professional job (see close up). There are no cracks in the notoriously crack-prone case which makes me think it can’t have seen much use with a neck strap. The main cosmetic issue is that the front panel has a dusty hue suggestive of long-term storage, I’m not sure if that could be cleaned up. There are some wear marks on the left side of the touch-sensitive keyboard. As is often the case with these synths, the battery case cover is missing (see photo of rear). The white tuning pot that is normally present under the pitch bend also appears to be missing (see close up) – I haven’t opened the Wasp up because I’m not technically proficient and didn’t want to risk inadvertently causing damage. The synth can still be tuned with the pitch bend pot.”

Octave Kitten

“Octave The Kitten Synthesizer Keyboard

Tested and is working.

I’m no pro synth user and it looks pretty complicated to work.

I was able to get some very cool sounds out of it but probably did not test all the functions.

Looks like it has a warped back bottom and maybe on the side panels.

As you can see it is missing a few slider plastic buttons but all the sliders move and switches move and seem to function.

If you know how to work it and want me to test a function let me know and I’ll see what I can do.”

Moog Polymoog

“A Moog Polymoog 203a analogue synthesiser, 1977.

In perfect working order, this synth has been professionally stripped, cleaned, serviced and rebuilt.

Power supply calibrated and tested, all PCBs cleaned, hundreds of solder joints reworked, many ICs socketed and replaced. It’s now very reliable and hardened to original polymoog transport issues. It’s clean and free of dust or dirt inside and out. All screws are present and original… absolutely no short-cuts.

There are the usual marks due to use.

All keys, LEDs controls and presets work as they should.” Click here to search for synths on eBay

Roland MC-202

“For sale is the much loved Roland MC-202. Pretty much a compact SH-101. It has a tiny crack (as shown in the pictures) which you probably wouldn’t notice and has no affect on the sound or operation in any way. Comes with power supply included. A true classic and a special analog synth.” Click here to search for synths on eBay

Roland Jupiter 4

“Classic Roland Jupiter 4 analogue synthesiser in perfect working order and good cosmetic condition.

The serial number is 105108, indicating a date of manufacture of September 1981.

A comprehensive review of the Jupiter 4, along with some videos can be found here:

Considering its age, this synth is in good condition. There are a few nicks and scuffs most notably to the side cheeks. One of the keys has a small burn and the paintwork is scuffed just below the LFO knob. All are photographed here.

This is a much loved and great sounding piece of kit used by 808 State, Vince Clarke, Depeche Mode,Thomas Dolby, Human League, Gary Numan, Tears for Fears, Stevie Wonder and Vangelis

The time has come to reluctantly let go of this and a few other pieces due to the demands of family life. I’ve been a semi-professional bass player for many years and can’t justify keeping a synth like this. But I’ll be sad to let it go.” Click here to search for synths on eBay

Roland TR-707

“Working vintage drum machine in good cosmetic shape. Does have a crack in clear plastic screen, pictured and some adhesive tape residue from previous owner. I have owned and used this machine in my smoke free studio for the past 15 years. Original power and manual included. Battery compartment is clean. Continental US bids only please.” Click here to search for synths on eBay

Roland TR-606

“Roland TR-606 with original carrying bag. Has individual outputs for each sound. Also has three other mods which I have not messed with. I assume the mods are cymbal decay, snare decay and Kick decay. They can be adjusted with a tiny flathead screwdriver. Sounds like a normal 606 as it is. All sound generators, buttons, knobs and functions work perfectly. No corrosion in the battery compartment.” Click here to search for synths on eBay

Roland D-50 Project Machine

“Selling my Roland D50 for Parts or Repair. I have tried to get this thing going, but I must be missing something.

The power supply has been rebuild to be the Caps were out of spec and some voltages were off. Also the key contacts have been clean. I have changed out the back up battery as well.

As you can see in the photos when the unit is powered on it loads and goes to what looks like the patch screen but it is call scrambled up. I have read on like were people reload the factory patches from a card, but I do not have any D50 cards.

Most of the panel buttons work, but they will all need to be cleaned. And you can see it is missing one key from the photo.” Click here to search for synths on eBay

Roland SH-09

“For sale is a Roland SH-09. It is working well but has a few noticeable issues. Mainly there are several scratchy pots and sliders. All functions appear to be working as they should except LFO mod on VCF or VCO (sorry can’t remember which one, I wrote notes on this before packing but now have misplaced my notes, but I recall there was an LFO mod section not operating properly). It could use a little maintenance to get it back to 100% functional condition, great project for someone hand with repairs. Due to issues it is sold as-is condition, no warranties or guarantees. There is some cosmetic wear as expected for its age. Check out the pictures to make sure you like it.” Click here to search for synths on eBay

Roland Juno 60

“We won’t get into the details of the synth – You’re here because you know it’s an 80’s classic.

Just inspected and serviced (new switch installed)

Unit works great! All switches, keys and sliders do what they are supposed to do.

Has some cosmetic blemishes, some on the face as shown and especially on the “wooden” end caps. Nothing that effects functionality. I would rate it a 7/10 cosmetically.” Click here to search for synths on eBay

Roland Juno 6

“The Juno-6 is a six voice polyphonic analog synthesizer! It’s a very stable synth thanks to its digitally controlled analog oscillators. The Juno-6 sounds great, however it lacks basic necessities like MIDI control and patch memory storage.
This is a vintage synth and does show some signs of wear on the chassis (pictured), but plays beautifully and sounds amazing! Refurbished with new fader knobs. Made in Japan.” Click here to search for synths on eBay
