“Full working order, lovely sounding synth but I am getting rid of anything I don’t use. This is the second one I’ve had and I bet I buy another in the future!

Works as it should. It has a battery mod (the mk1 Poly 800s don’t have internal batteries as standard) and it was retaining its settings last time I used it it. I turned it on to test it and it has lost its settings so I guess the battery is dead (I’ve not used it for ages), so I’ll include a new battery with the sale. ”

“Vintage Korg Poly 800 Polyphonic Analog Synthesizer in VERY GOOD WORKING COND!. I purchased this unit back in 1982 and has worked great since. It is missing the battery cover on that back and thE power supply is not original. I had an extra sega genesis power supply and it powered right up. This is a really nice keyboard. Has some cosmetic imperfections but overall very good condition, considering its age. ” Click here to visit listing on eBay

“This synth has been tested and sounds great!

It has been fitted with the Moog slayer mods for control of cutoff and resonance via the knobs on the side. There is also a third knob for FM. The order of these from left to right goes; cutoff, resonance, fm.

The only issues are that the battery cover is missing and the cap for the tune slide pot is missing.

Please see pics for further detail

Also be aware 9v power supply is NOT included in the sale” Click here to visit listing on eBay
