This is one of kind guitar effect. This circuit is used for produces loud noise for you guitar sound. This is the figure of the circuit.
The Maestro Fuzz is reputed to be the fuzz used in the recording of the Stones’ "Satisfaction". The transistors are house numbered "991-002298" and the diode is house numbered "919-004799". They are probably all germanium devices. The use of a squelch device is somewhat unique, possibly put there to tame hiss and noise during quiet passages between notes. The two 50K pots which have their wipers connected by resistors are wired so that as one increases, the other decreases, giving a pan from one point in the circuit to another, probably changing the amount of distortion. The last 50K pot is an output level control.
