Korg X-911 Project Machine

“Partially working with faults!

Instrument side:
Elec Bass LED always on (doesn’t Cancel) No sound either from this preset.
Tuba never switches on, so no response from this one either.
the other 4 work as intended, including trim pots.

Synthe side:
LEDs will light & cancel, but none are sounding.

I have a feeling this will centre around the filter chip rather than the buttons. Similar to the common fault in the Korg Delta. The parts are still available.

The left hand side of the panel is fully working, input, portamento/ interval/ tune/ octave all 100% on the 4 working voices. Still great fun to be had with this alone! Glitchy, Prog-type fun & Octave effects a-plenty!

Synthe filter knob not working, again pretty sure this is related to the synthe side. Possibly these tones go through the filter chip & the instrument side is filtered by resistors etc, as you have no control over those.”

Korg Poly-61M

“For auction is a storage sale find of a KORG POLY-61M Synthesizer. Item powered up fine and I was able to get sound from all keys. I was also able to make various cool sounds at different settings. That’s pretty much all I can say as I’m no expert in synthesizers, much less a musician. Please take the time to review all the pics and watch the video so you can get a better feel as to what’s being offered here.” Click here to search for synths on eBay

Korg Polysix

“230V, no MIDI. Some dents on the wooden sides, minor scratches on the front panel. I tried to spot all of them. They’re not very visible. It looks very nice, works flawlessly and sounds beautiful. Overhauled last year, no battery issue, no scratchy pots, no sticky keys. I kept it in a soft case which I’ll give away with it.” Click here to search for synths on eBay

Korg Poly 800

“Spectacularly preserved Korg Poly 800 analog synth with hard case, original manual, original factory preset cassette tape and original power source. We recently purchased it from Switched-On in Austin TX and it has been fully serviced. It can be battery operated and has pegs so that it can be strapped on and played as a keytar (awesome). ” Click here to search for synths on eBay

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

Yamaha FB-01

“Classic Yamaha FM synthesis right here in a box.
I’ve hooked this up and played through most sounds in several banks. Seems to work just fine.
I don’t know about any of the memory functions.
Definitely in used condition. Housing shows wear and scratches.
MIDI and output connectors seem to be in good shape still.” Click here to search for synths on eBay

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).

Case shows wear but machine works flawlessly, a pleasure to use and gives you that 12 bit crunch and ring on pitched down samples that only this machine and the SP1200 can do.” Click here to search for synths on eBay
