Rare, late-70s Electro Harmonix "speech synthesizer" pedal for sale in excellent working order - great formant filter effects.

If you think of it as a talk box / wah then you are some of the way there. Great with synths.

Calibrated and working well.

CONDITION: Like all early Electro Harmonix pedals, it's built like a tank. In very good cosmetic condition with some signs of wear or age. Feet are new replacements. See photos for more information on cosmetic condition.

Takes one 9v battery (included).
