Custom Dual Germanium/Silicon Fuzz with Filter Control

This is a custom fuzz pedal with a pair of germanium transistors, similar to our standard germanium fuzz, but with the first transistor switchable to silicon for extra versatility.  Not only the extra silicon transistor gives a fantastic alternative tone, but it can also be very handy when the ambient temperature is less than ideal and you want extra stability.  The pedal is fitted with an external bias knob, on top of the classic Volume and Fuzz knobs, to help compensate for the variation between the different transistors.  Additionally, a Filter control is included for controlling the circuit’s low end, adding tremendous versatility to the pedal; the woolly low end of the circuit can be a little overwhelming with certain setups, and being able to control that is very useful.  Also included is a toggle switch on the back for disconnecting the internal battery without having to unplug the pedal.
