2-Voiced Diode Fuzz Circuit with 3-Band Tone

2-voiced diode-fuzz circuit with 3-band active tone and 4 stages of gain. Controls Include: Input Gain, Input Attenuation, Drive 1, Fuzz 1 enable switch, Fuzz 1 symmetry switches, Fuzz 1 Depth, Fuzz 2 enable switch, Fuzz 2 symmetry switches, Fuzz 2 Depth, Drive 2, Bass, Mid, Treble, and Volume. The Fuzz voices are from (1) standard silicon diodes in a shunt-type array, and (2) Schottky diodes in a feedback array. The symmetry switches set the harmonic content of the fuzz. With both Fuzz Arrays disabled, the circuit will perform as a high-gain booster with 3-band tone. Fuzz 1 has little affect on total gain, though it should affect the sound of the signal (by clipping), but Fuzz 2 will cut total gain by as much as -2.5 dBV. Frequency range is from 40 Hz to 16 kHz with all controls at 50%. Suitable for 6-string electric guitar (not for 7/8-string guitar or bass-guitar). Maximum gain = +26.6 dBV @ 1 kHz with all controls at 50%, and more than twice that with all controls at 100%. Power-supply not shown. Requires a regulated dual-polarity DC supply providing +-9VDC or +-12VDC or +-15VDC at >= 40 mA of current. And while simulator verified, treat the circuit as experimental. Breadboard test before soldering.
