Up for sale is a very cool Casio synth. Sounds absolutely killer and works great despite some abrasions and the one key taped on. 😂 yes it is taped on but works fine. I tried finding a replacement but struck out. Maybe You’ll have better luck.

The Casio CZ-1 is a legendary 1986 flagship digital synthesizer utilizing Phase Distortion (PD) synthesis. As the most professional model in the CZ line, it features a 61-key velocity-sensitive keyboard with aftertouch, 16-note polyphony, an onboard analog chorus, and robust patch memory storage.
