I recently built a modified clone of a Marshall Supa Fuzz from a board for a Tone Bender Mk. II. The circuit has a charge pump to supply power and provides negative ground at the jacks.The schematic also calls for a 1 M pull down resistor. This is a modern touch to prevent popping when turning the effect on. Otherwise it’s pretty much a classic Tone Bender circuit. You can find the pcb at: GuitarPCB (more…)
