Very rare 6-stage optical phaser with LFO or envelope controlled phasing. Highly regarded for its unique combination of a lush analog phaser and an onboard envelope follower, housed in the classic large-format "trapezoid" metal chassis. Unlike standard phasers, the vintage Polyphase uses light-dependent resistors which contribute to its smooth, "liquidy" tone that is difficult to replicate with modern components.
Modified to run on 15-18VDC(C+), otherwise functions normally. Power supply NOT included.
