“You are bidding on a Korg Poly-800 synthesizer for parts/project. This synthesizer was working, but had been partially disassembled to install some modifications (moog slayer,) which were not completed (only knobs/pots installed.) It has sit on a shelf for some years waiting to get the attention it deserved, but unfortunately I have not been able to find the time for it, and I must now regrettably let this awesome synth go. I hope it finds a new owner that can give it the attention it needs.

Please understand that this is a PROJECT synth that will require some work (or to be used for PARTS for another poly800 project.) With this in mind it is being sold as-is, so bid accordingly.” Click here to visit listing on eBay

“Excellent condition fully functional

Serviced by professional synth technician

All keys removed, mechanisms lubed and keys washed

Weak solder joints reflowed, all switches, sliders, pots etc cleaned

Modified to accept two Internal 3V coin batteries, rather than the C batteries on the back… wired in parallel, so voltage stays 3V but maximum Ah is increased — this is a significant upgrade because when replacing the batteries, you can change one at a time, so that you NEVER lose your patches when changing batteries unlike how it works with a stock Poly-800 with the C cells (which are connected in series, so when one battery is removed the ENTIRE patch bank is lost)

Comes with hybrid case, mono cable (for dumping patches to tape/flashing synth with patches), power cable, 2 midi cables, ORIGINAL PATCH BANK TAPE (note: the patch bank tape doesn’t seem to carry a strong enough signal to flash the synth with patches. However, when using the patch banks available on the internet, like on Youtube and Soundcloud there was no issue flashing the synth)” Click here to visit listing on eBay

“Offered is a Korg Poly 800 Keyboard Synthesizer made in Japan. Korg built the Poly 800 from about 1983 to 1987, so it’s from sometime then.
This 49-key synth is a great addition for musicians and producers who want to create unique sounds.
The instrument is sold with a Calzone Flight Case that ensures safe transportation. The case is covered in stickers. The case handle, latches, and hinges all work fine.
It comes with a non-original, but proper, power cord.
When plugged in and turns on, nothing happens. Nothing at all. I have done nothing to it. I did open it up. It appears to be unmolested and all there.
Thus, it is being sold as a non-working REPAIR PROJECT. ” Click here to visit listing on eBay

“This is my beloved Korg Poly 800 – I bought it when it came out and it’s been with me since.

As a synth it works perfectly well, the only problem is that as I left the batteries in for too long they oxidised, and as a result part of the battery bay and part that connects from there to the circuit board has been eroded a bit by that. As a result of this and the internal battery also being depleted, the machine currently won’t hold settings/presets after being switched off.

I have tried to fix that, and in doing that I did manage to have it on just with the batteries (as you can see from one of the main picture in this listed, where it’s on while not connected to the mains) – but the fix I did was a bit flimsy and didn’t last long. I am sure that some capable hands can sort this out very easily – I am just not that technically/manually minded so not the best person to do that kind of soldering etc.

I uploaded the full set of presets using a soundfile that mimics the original Korg tape and while a bit hit and miss, it did work a couple of times, so that function also seems to work fine – it just won’t hold them unless it’s left on, or the battery thing is fixed.

I also developed a sound just to check that the various parameters work OK and they did – see the video included in the listing (apologies, as I had no time to hook it up to an amp the sound in the video comes from the headphones).

Other niggles:

– the top of the wheel is missing
– the chassis has a few marks here and there – see pictures
– a key is not working – circled in red in one of the pictures
– the bottom side of a key is slightly chipped – see pictures

Otherwise tin relatively good state considering its age – now just waiting for its next, second owner who will take care of it and bring it back to full functionality after it’s been with me for a large part of my life.” Click here to visit listing on eBay
