Yamaha DX27

“I am selling my vintage Yamaha DX27.

It is fully working but does have some cosmetic damage on the bottom and a little on the top. Nothintg series, there are no dents or cracks in the metal case just some scuff and scratch marks. This keyboard is 32 years old and based on the same technology as the famous DX7, but does not have the DX7’s power.

All the keys operate and test fine.

I have tested the keybaord but i don’t have a power supply to include with the sale. It will work with most 12volt power adapters.” Click here to search for synths on eBay

I’ve hooked this up and played through most sounds in several banks. Seems to work just fine.

Sequential Circuits Pro One

“I am reluctantly selling my Pro One. Between a friend and I we have had this classic for over 30 years.
Serial No 100- 4403
It has been in storage for several years and after plugging in to test, it has developed a couple of faults,

I want to be honest so I will list what the obvious defects as well as the good points to give everyone a good basis for decision

Cosmetically it is still In great condition for a big old monosynth from 1981
It will power up . the on/off switch on the back is stuck in “on”
The synth will work in drone mode , the keyboard does not appear to work.
The knobs and pots all seem to work ok, a few are a bit noisy , in drone mode you can hear the filters change, LFO etc
Both the pitch bend and modulation wheels work ok.
The keyboard has a few slightly wonky keys, but the last time it worked, all the keys worked fine.
There are scratch marks to the bottom of the casing from being on stands etc over time
The front panel is in very good condition with very few visible blemishes
The wooden end cases are also in good condition.
I have replaced the fuse holder and replaced the fuse, and I have downloaded a manual with the original 20 preset patches

I have taken the Pro One to a private keyboard repair centre, the guy seems to think it’s a voltage problem, but 35 year old mono synths were not his strongest point, but he said it would definitely be salvageable with the right knoweldge. ” Click here to search for synths on eBay

ARP Odyssey

“RAREST of the RARE: ARP Odyssey Mk I (Late Model 2800-1974-5). This is a two-oscillator analog synthesizer, and one of the first with duophonic capabilities (the ability to play two notes at the same time). This allows you to get that wonderful “guitar-like” distortion when used with Distortion/Flange effects.that bands like Ultravox used to good measure as a lead synth.
I used this in my home studio back in the day before it went into temp-controlled storage. NEVER USED ON THE ROAD/GIGGING. Smoke-Free environment always. Hence the museum quality condition. Please look at the pictures-Even the slider caps are all original!

I just had a full, cost-no-object service completed by one of the top analog synth techs in the USA (see some of the sample parts replaced in last pic): Trim Pot, Filter Caps, Sliders, etc. – Including a full set of Key Guides – so plays AS-NEW! NOTE: This is not a Mark II, even though it is Black, not White. Late models were done like this, hence there is no CV/Gate on back panel. Like I said, Super Rare. ” Click here to search for synths on eBay

ARP Axxe Project Machine

“Up for sale is this ARP Axxe.

I bought this secondhand so I’m unsure of what happening on the inside. Modifications have been done as far as I can tell by the back panel.

It powers up and sound comes out. Most functions work as they should but some sliders are a bit scratchy and the effect can jump about.

Things I know aren’t working are:

-The keyboard isn’t gating properly. When key is released a note is still in playing.

-CV jack on the back not working.

-Sample and hold switch not working

-Portamento” Click here to search for synths on eBay

Emu SP-12 Turbo 2.6

“Emu SP12 Turbo 2.6, Brought back to like new condition by Bruce Forat in LA in January 2016, used sparingly in my smoke free home studio triggered by another machine. 8 new audio outputs added, sample pot replaced and pcb traces repaired, all new numeric pad buttons replaced, pads replaced/reconditioned as needed, new battery, Noritake fluorescent display added, vinyl repro faceplate with small printing error (no start lettering under start button).

Casio SK-1 Ciruit Bent

“Very versatile well built and bent vintage Casio
. Great for experimental or electronic music. You can get a lot of different patterns & glitches from the patch bay ..If you have never used one ..no fear! the simple explanation is use a banana cable and patch. Go for it no wrong way . I’ll throw in a couple cables to get you going.

To use this synth you will need banana cables ,and a Boss style 9v power supply.The builder pulled the speaker and added a 20 point banana plug patchbay. 1/4″ output jack And 9v input .

As you patch the points together it glitches out Sending the SK-1 OFF COURSE .Without patching it will work as a stock SK-1. Not so pretty but it really is a unique monster ! The reset button does not work so well so I just shut it off if reset is needed. ” Click here to search for synths on eBay

Marion Systems MSR-2

“That’s a video of the Marion ProSynth that I found on YouTube. The ProSynth is the non-expandable single voice board version of the MSR-2. It sounds about the same but the MSR-2 has some more options, such as filter inputs.

Comes with a printed manual, but the manual can also be found online.” Click here to search for synths on eBay

Grendel Drone Commander

“Bought this awesome and unique synth for a recording project, but now I need to part with a few incredible pieces I can’t afford to keep.

The sound this puts out is dreamy and heavy. The filter is a beast.

These are getting to be VERY rare and hard to find. It’s the only one on eBay and it’s been a while since I’ve seen another listed. Buy it now!

What you see is what you get, and since I’m not an expert on this thing it’s being sold as-is, but it definitely sounds fantastic on the album we just made.” Click here to search for synths on eBay

Grp Synthesizer A4

“Italian made GRP A-4 Analog Synthesizer.
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.
I had a Voyager XL, and for similarly priced units, the A-4 blew it away, so I sold my Moog. The GRP has much more power and flexibility and the fidelity is superior to the Voyager, IMO. 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 me. 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.

You will notice one small blemish in the last photo. This is NOT a scratch, merely a narrow SMUDGE (about 1/2 inch) that can easily be covered with the matching stain from a Minwax Wood Finish Stain marker pen. The cabinet appears to be a walnut veneer. Other than that, the unit looks brand-new. I am second owner, neither of us were smokers, home studio only, never live gigged, super low hours, only we touched it.” Click here to search for synths on eBay

Akai VX90

“For your consideration I have a ultra rare AKAI VX-90 rack. It sounds amazing and is 100% functional. It comes from a clean smoke free home. It comes with the original rack ears and hardware. This is a VCO synth with a lot of cool features. All of the waves have pulse width. You can stack half or all of the voices in unison and then detune them for a super fat sound. Its really easy to edit from the front panel. It also has an input to process external audio form AKAI samplers. The only thing worth mentioning it that the power cord has been shortened to fit in a rack, it does not affect the synth whatsoever.” Click here to search for synths on eBay 

Octave Cat SRM II

“This one is brand new in the original box with the manual + brochures. It is working 100%! Prior to the listing, it had been calibrated as it’s been sitting wrapped in it’s box for over 37 years. I have several available! This model is last of the series, the SRM-II. It uses CEM 3340 (oscillators) and a SSM 2044 (filter). ” Click here to search for synths on eBay
