2-Voiced Diode Fuzz Circuit with 2-Band Tone

2-Voiced diode fuzz circuit with 2-band active tone-control. The Fuzz voices are; normal soft-clipping fuzz from standard silicon diodes in a feedback array, and germanium-like hard-clipping fuzz from Schottky diodes in a shunt-type array. Controls Include: Input Level, Gain, Drive, Fuzz 1 enable switch, Fuzz 1 symmetry switches, Fuzz 1 Depth, Intensity, Fuzz 2 enable switch, Fuzz 2 symmetry switches, Fuzz 2 Depth, Bass, Treble, and Volume. Note: The symmetry switches set the harmonic content of the fuzz from a given array. Symmetry between the two legs of an array emphasizes odd-order harmonics, while asymmetry emphasizes even-order harmonics. Range between high and low -3 dBV corners is from 16 Hz to 5.5 kHz with all controls at 50%. Range at or above 0 dBV is from 18 Hz to 4.8 kHz. The 20 Hz standard high limit is down by -35.4 dBV. Range extends with controls set higher than 50%. Maximum gain = +31.8 dBV @ 250 Hz with all controls at 50%, or +71 dBV @ 160 Hz with all controls at 100%. Circuit is suitable for 6/7/8-string guitar or 4/5/6-string bass. Power-supply not shown. Requires a regulated dual-polarity DC supply providing +-15VDC @ >= 40 mA of current. And while simulator verified, treat the circuit as experimental. Breadboard test before committing to a soldered build.
