2-Voiced Diode Fuzz Circuit with 3-Band Tone-Stack

2-voiced fuzz circuit using two shunt-type diode arrays with different diodes, plus a 3-band Fender-style tone-stack. Note: This is a high-gain fuzz circuit. Controls Include: Input Gain, Input Level, Bass, Mid, Treble, Boost Gain, Drive 1, Fuzz 1 enable switch, Fuzz 1 symmetry switches, Fuzz 1 Depth, Drive 2, Fuzz 2 enable switch, Fuzz 2 symmetry switches, Fuzz 2 Depth, Output Gain, and Volume. Frequency range at or above 0 dBV with all controls at 50% is from 87 Hz to 18 kHz, or 50 Hz to 100 kHz with all controls at 100%. This is ideal for 6-string electric guitar in standard tuning, with emphasis on the mids. Not recommended for 7/8-string guitar or bass-guitar due to lack of low-end reach. Maximum gain = +44.1 dBV @ 630 Hz with all controls at 50%, or +79.9 dBV @ 1 kHz with all controls at 100%. Power-supply not shown. Requires a regulated dual-polarity DC supply providing +-9VDC or +-12VDC or +-15VDC at >= 30 mA of current. And though simulator verified, treat the circuit as experimental in nature. Thoroughly breadboard test it before committing to a soldered build.
