Vintage Casio CZ-1 synthesizer in great shape for its age. The most advanced keyboard of all the CZ series phase distortion synths with 16 voice polyphony. Missing one slider knob, but everything works. Velocity sensitivity keys are a joy to play and add a ton of expression to your playing. Hard to go back after that. There’s one key that requires an ounce more of a touch to fire (typical for a unit of this age), but a technician informed me this could easily be fixed with a routine cleaning of the rubber contact points. Venmo/PayPal accepted. Thanks for looking!
