Fuzz Face guitar effect pedal schematic diagram
The original schematic isn’t exaclty what is shown above, it had a pretty complicated switching system that has been simplified (certainly nothing has been missing don”t get worried) and a different grounding setup. Aside from that, the schematic is precise with small variations in components on several units (eg. some component had the 0.1uf capacitor listed as .047uf, which shouldn”t cause a difference as long as you feed a high impedance amplifier). The transistors are difficult to get, the thing to try to find is germanium transistors which has decent gain factor (gain > 80).
