“1983 KORG Poly-61 Poly61 Vintage Analog Synthesizer For Parts or Repair
“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.”
“I have been the sole owner of this synth and have kept it in excellent condition. I have tested every slider, knob, pot, and key, and everything is fully functional! When I opened the case to inspect the components, I was pleased to see that it was nearly spotless. (See pics) The battery is old but in great shape and when I put it on the meter, it maintained a steady 3.3 volts. (Brand new it is rated at 3.6 volts.) All patches are intact and fully functional. The carbon contacts that sit under each key had oxidized with age, as would be expected, so they have been restored and all 61 keys work perfectly. I also connected the MIDI input to my Korg M1 and was able to trigger the Poly-61 as intended.
