“This pedal was made for Univox in Japan in the 1970s. It is a very early example of a volume /wah pedal and among the first, if not the first, to use a lamp and photo resistor instead of a standard potentiometer. This gives it a very smooth and unique wah-wah sound. You can also easily disable the wah function and use it as a volume pedal. This is truly a piece of early Rock and Roll history.”
