An electronic instrument developed in the Spellcaster Lodge QElectronics laboratory, only 44 units hand-assembled by Quintron exist.
Its four voices – Space, Snare, Bass and Kick, are triggered by activating a photoelectric cell either intermittently or with an on/off DIP switch in combination with exposure to light.
[1] The Drum Buddy is outfitted with a light fixture on a periscopic pipe fixed to its base.
As the can rotates, its holes pass the Drum Buddy's photoelectric cells, firing drum-like tones and theremin or Moog synthesizer-like chirps or buzzes.
Accomplished purveyors of the Drum Buddy can operate the instrument freestyle by "scratching" the can back and forth against the resistance of the platen's motor or by performing short solos on the bass channel's 12-point chromatic scale.
