Univox Super-Fuzz Pedal

This is the circuit diagram of Univox Super-Fuzz Pedal. This pedal is actually a 69-to-early 70″s design that consists of two special capabilities. They are the octave generation effect from the differential-pair-with-collectors -tied-together along with the option of just a clipping amplifier or a 1kHz notch for different sounds.

The odd-diffamp is basically a full wave rectifier as applied in this circuit. The clipping is all completed using the pair of back-to-back diodes just before the normal/notch filter section. These were basically germanium, even though silicon will work. You are able to use LED”s here for a various sound, but you will need lots of gain within the input to obtain adequate signal to them to break them over.
