CIRCUIT DESCRIPTION
The Maestro Fuzz, powered by an internal 9 volt battery,
generates low order odd harmonic distortion by using silicon
diodes in the feedback circuit of an operational Amplifier.
Refer to Figure 3 for the schematic diagram.
Either the fuzz mode or straight Guitar is selected by foot
switch SW1. In the fuzz mode, the input signal from AXE jack
J2 is a-c coupled to inverter IC1A, the output of which
feeds DRIVE pot R6. Since the distortion circuit following
R6 is level sensitive, R6 acts as a distortion amount
control. The distortion circuit consists of IC1B, CR2 and
CR3. Diodes CR2 and CR3 in the feedback path of IC1B cause
symmetrical clipping of the input waveform generating the
desired distortion. The distorted signal is a-c coupled to
VOLUME pot R9 which controls the Maestro Fuzz output level.
In the straight mode, SW1 shorts the Maestro Fuzz output to
ground minimizing fuzz circuit bleed-thru and the input
signal is connected directly from AXE jack J2 to AMP jack J1.
