MAZZY FUZZY 2in1 "Masami Tsuchiya x Endroll" 2 in 1 specification with FUZZ (OVERLOAD) on the left side and PUMP-UP BOX on the right side. Distortion is created by mounting a silicon transistor BC108C x 4, which has become rare in recent years, and clipping it with a germanium diode after gaining up. By raising the HIGH of TONE further than the white LED at the 4 o'clock position of the clock hand while driving OVERLOAD, a powerful Fuzz sound is produced.
