“Up for consideration we have a Rare Vintage 1970’s SWTPC Psych-Tone Composer-Synthesizer, Untested. This Psych-Tone Composer-Synthesizer measures 10 3/8″x 7 1/2″x 4 5/8″, and comes with a 60″ cord. This Synthesizer is untested, and missing its back, but looks very cool. The Psych-Tone was basically a random note generator that used three twelve position rotary switches and three knobs to vary the pitch of an oscillator. The oscillator output went to a tone shaper and then an envelope generator/VCA.” Click here to visit listing on eBay
