Fuzz Face
The Fuzz Face can be built in silicon, germanium and hybrid (one silicon and one germanium) versions with a range of possible mods and controls, the most common being Volume, Fuzz, Pre-gain, Tone, and Bias.
Silicon:
Transistors are normally BC108/9, BC183L or similar NPN types. An NPN circuit which is powered by either 9v battery or 9v power supply.

Germanium:
Transistors are normally 2N404A, AC128/AC125 or similar PNP types. A PNP / positive ground circuit which is normally just built with battery power. A DC jack can be fitted on request, but will require it’s own dedicated power supply which can’t be daisy chained with other NPN pedals. A voltage converter can be fitted to allow daisy chaining with NPN pedals on request.

Hybrid:
These can be built in either negative or positive ground versions, with the usual options.
Price: Ranges between €85.00 for a 2 knob silicon on veroboard to €125.00 for a 4 knob germanium on tagboard. Contact me for details.
