Vintage Morley stereo optical volume pedal. Mains (240V) powered, although this purely operates a small bulb via a step-down transformer, so could easily be modified to use a battery or external DC power. It’s a passive pedal, using a pair of light dependant resistors (LDRs) to smoothly attenuate both signals, depending on the position of the pedal and a cloth curtain between the small light bulb and the LDRs.


This rare and collectible pedal is in great condition, both functionally and cosmetically.

Collection from Somerset, or I can post well-protected & insured for £15.
