"super rare 1/600 Sonica Limited Edition Synthesizer made by Frank Eventoff in Los Angeles in the 70's. In excellent condition, although the thin foam membrane covering the speaker has disintegrated and can and should be replaced. There are two small dark streaks on the brass near the half-step button that are minor original blemishes. The case is included as well as the original paperwork. This is a fun little unit for jamming on and is very easy to play. The output jack is a strange 1/8" that I haven't found the exact right plug to fit it. I have just played the internal speaker and recorded to mic.
Some info from the documentation:"The Sonica is a portable self contained synthesizer designed to simplify the playing of music... an electronic sensor that converts the pressure of your touch into creative musical tones and expressions... carved from Red Alder, a domestic hardwood. several coats of lacquer. Finished by hand. The face and trim are solid brass protected with baked enamel finish. " Serial Number 592, one of last ones made!"
