"The backstory with this instrument is that I bought it used in Feb. 2020, replaced the keybed with the drop in replacement from Techsmechs, and then had it tuned and calibrated by Matt at Futura Electronics. I then traded it to a friend who didn't use it much for the past couple years. Then I got it back over this past summer.

Cosmetically, it's particularly nice and I'd even say a cut above the rest. Very few signs of use at all. This is a higher serial number, made in September of 1983, hence why I had to replace the old membrane keyboard.

Functionally, it's working great and it sounds beautiful. Just give it 30+ minutes to fully warm up just like any other vintage analog synth. All ins and outs are working as they should. Sold AS-IS, as described in vintage working order."
