This is a fuzz pedal that adds a touch of gloss and a slightly thicker distortion to the Jimi Hendrix fuzz sound. A friend sourced the original parts, and it was assembled in a workshop. It's point-to-point wiring. The internal trim pot allows you to increase or decrease the amount of distortion. ↑ The sound was as described above, but when I connected it recently, the sound quality had changed. It produces sound, but the nuance is different from when I used it, so I'm listing it as junk. Thank you. m(__)m
