"Rare 1970s Music Technology, Inc (Crumar) CPB-2 foot pedal analog bass synthesizer, made by Elettronica in Italy. This warm, thick, and great sounding analog foot bass has very useful synthesizer features that allow for a wide range of timbral possibilities, all of which have great sonic integrity - some compare this model to the Moog Taurus for sonic similarities. Features Tuner knob (has been replaced/repaired - is now a continuous pot, but still functions); VCF Envelope, Cutoff, and Resonance knobs; Release switch - allows a note to cutoff with the release or to ring out at 100% until next note is triggered; Doubling switch - a nice chorus effect; Footage switch - selects high or low octave; Waveform switch - selects sawtooth or triangle waveform; and sustain and master volume wheels in nice vintage orange. The master switch is a bit finicky as a piece of the plastic is broken off, but it still functions (if gigging, I would recommend taping it in the "on: position and unplugging the cable to power off). All else is perfect working order and all original. A great sounding vintage Italian analog foot pedal bass synthesizer - a perfect tool for production in the studio or as an added bass instrument on the road. Power cable included. Perfect gift for the holidays!"
