Korg Poly-800

“This is a used Korg Poly-800 synthesizer keyboard. The keyboard turns on, but only a few of the preset sounds work and I am not sure these are the actual Korg programmed sounds so I am selling for parts only. All keys function properly, volume control, sliders, buttons and joy stick work. Power supply included.”

Korg Poly 800II

“For sale is a Korg Poly-800 MK II.
The synth is in good operational and cosmetic condition.
The only minor issue is with the numeric keys ‘1’ and ‘2’ which sometimes double trigger when pressed. Might need some cleaning or replacement but I don’t have the time to deal with it.
Other than that there are no more issues with this unit.
The synth comes with a universal aftermarket power supply that I spliced to make the cord longer. Works with both 110V and 220V power grids.
This is a really cool synth with a distinct 80’s sound. ” Click here to visit listing on eBay

Korg Poly 800

“1980s Korg Poly 800 Synthesizer 80s synth

Comes with original power supply. Works great, sounds great. Very underrated keyboard. There are mods that can make these even cooler than they already are for very little $$

Has some normal cosmetic wear, especially on the corners. Plastic color has faded and chalked out in some places. All keys and functions work well.”

Korg Poly 800

“The power comes on with AC adapter. It is unknown whether the sound comes out or not, because the memory is off. When you start the sequencer, you can hear the sound of the sequencer.
The joystick cannot be held in the middle because the spring seems to be off. 
There are many bald spots on the paint. Around the edges, buttons, and switches. ” Click here to visit listing on eBay

Korg Poly 800

“A vintage KORG POLY 800 synthesiser in great working order.

This classic early 80s synth is extremely clean and tidy, everything works, and nothing is wobbly. There are no suspicious ‘burns’ on any of the keys.

There are the usual marks from forty years of use, and there is a tasteful replacement joystick knob.

Complete with alkaline C cells for testing! No other accesssories included.”

“Vintage Korg Poly 800 Mk1 Analogue Polysynth, PSU, & Original Data Cassette.

A great sounding early eighties original polysynth with six voices. Great condition.

This one is unmolested. There are a few well known DIY modifications possible if you’re any good with a soldering iron and a drill. I’ve preferred to leave mine unscathed.

Only one thing to be aware of: Pitch/Mod joystick only works in the Y (modulation) direction and does nothing when moved in the X (pitch) direction. This has never been an issue for me in the years I’ve had it as I’ve always controlled it remotely over MIDI.”

“Collectors item! There are plenty of these on the market but rarely do they come up in such superb condition.

Apart from a barely noticeable hairline scratch on the corner and a tiny nick in the joystick plate, also hard to spot, the keyboard is in really mint condition throughout. Please see extensive photos.

There is no wear around the volume knob or other controls, the display is mint, the plastics are possibly the cleanest and best condition you will find anywhere, both front and rear.

Comes with original power adapter, patches cassette tape, and the all important preload program list which includes patch data. Also this is in its original box!.”

Korg Poly 800

“Korg Poly-800 Polyphonic Analog Synthesizer Beautiful condition With Stand & Power supply and batteries.
I bought this from a person a few years ago who swore it was essentially unused since the late 1980’s. I needed it to record two songs and now I have no use for it. It has been kept in a case but I am not including it in the listing since it is made from heavy wood. I bought an ironing board style stand for it and I am including it as well” Click here to visit listing on eBay

Korg Poly 800II

“Based on the condition, might have played just to test long time ago then stored after. Looks like new. Only 2 small dent on the back.

A rare chance to own a barely used piece of synth history! In the original box, original manual, power supply and data tape. Replaced the internal battery and reloaded the factory data. It looks and plays wonderfully. Battery compartment is clean. Thank you for looking!

Fully tested and works like new! Includes everything in the picture. It will be double box. ”

“Korg Poly800 Vintage Analogue 8 Voice poly synth with Atomahawk capabilities.
I’m flogging this as there are a couple of issues but this is totally useable and still sounds
amazing so please read on.
Sound engine and all keys function as they should. The only issues are as follows;

1. When using the LFO stick on the left of the synth, it doesn’t physically stick but the LFO stays activated.
This has never been a problem for me as I don’t use it.

2. The ON/Volume knob is a bit iffy. Once you’ve switched it off, you’ll need a few attempts at switching
it back on. I just leave it up permanently and use the mains to switch on all my gear anyway, so again,
has never been an actual problem for me.

3.Now, this synth has the Atomahawk upgrade but I wanted to just use it in its original state so I
disconnected the unit inside the synth so that I could use the original parameters. This worked but a few
of the parameters numbers don’t correspond to the parameters board located on the top right of the synth.
To get around this i have put some sticky labels to remind me what numbers to punch in to change the
settings.” Click here to visit listing on eBay

“Here’s a 1980s Korg Poly-800 polyphonic synthesizer in good playing condition. This machine is a little funky to program but once you get the hang of it you’ll find that it’s loaded with a wide variety of lush and dynamic tones, and the design is nice and compact and well made. Very cool! Sure to make a great addition to your studio or live setup. Some normal cosmetic signs of use throughout (see photos), but this one is in very good shape overall.” Click here to visit listing on eBay

Korg Poly 800 Project Machine

“Up for sale is a Korg Poly 800 from the early 80s. It works but has a few issues, at some point, someone removed the write “program enable/disable” switch from the rear of the unit

and moved it to the top of the unit in the form of a mini toggle. It still works to save patches, but has to be massaged just right. All the original patches have been wiped clean, so every available patch (save a few that I’ve programmed) will need to be created to your liking and saved. There is also an added RCA plug and knob control (don’t seem to affect anything). All the keys, modulation stick (awesome) and editing functions, adjustment controls seem to work fine. I have not tried any sequencing or MIDI. Basically, this synth works but is not quite in fully working factory condition. It may need repair to fully perform as intended and is being sold as-is as a project, or for parts. There are fresh batteries installed so all patches created have the ability to be saved.
