Vintage original Jen Double Sound Distortion/Wah in good condition. Made in Italy. Pedal has obvious signs of wear but sounds and functions great. Treadle rolls smooth. "Distortion" part of the circuit resembles a fuzz-face.
Jen built pedals for Vox and Gretsch in the late 60's / early 70's as well as marketing pedals under their own name. They are best known for developing the Cry-Baby wah pedal circuit.
