coll circuit

This is a design for guitar effect. This circuit is used for produces fuzz sound, so it is called fuzz effect. This circuit is built by low noise dual op amp IC and transistor. This is the figure of the circuit.


The GEU is good sounding octave fuzz, with an optional mode of just fuzz. The fuzz is a fully rectified signal and is quite chewy. For some the Fuzz alone might not be loud enough, this can be fixed by raising the value of the 820 ohm resistor and lowering the 39k one. Or one could just replace both with a normal volume pot for a more standard approach. The "struzz" is the fuzz with an octave higher signal mixed in. Good for signal notes and leads.
