Casio CZ-1 Synthesizer made in 1986. The flagship of Casio's legendary CZ series and one of the most expensive phase distortion synths ever made. Offers 61 velocity and aftertouch sensitive keys. Rich evolving pads, punchy basses, glassy digital bells, and Blade Runner 80's synth sounds. Fully functional but the middle A key can be a little temperamental. It works but requires a little extra push compared to all of the other keys. Not noticeable at all in my opinion and probably just needs a cleaning to be 100%. One of my favorite synths I own but I am saving up for a big studio purchase. Contact me with any questions!
