2-Voice Hybrid Fuzz Circuit 2 with 3-Band Tone

2-Voice hybrid diode + JFET fuzz circuit for guitar, with 3-band tone. Fuzz voices are from two arrays with different devices; one feedback-type Schottky array with dedicated op-amp, and one shunt-type JFET array (using JFETs configured to work as diodes) with a separate dedicated op-amp. The "hybrid" designation indicates use of both shunt type and feedback type arrays, along with the two kinds of clipping devices. The fuzz voices are meant to sound modern, with Fuzz 2 softer than Fuzz 1. Controls Include: Gain 1, Drive 1, Gain 2, Drive 2, Fuzz 1 enable switch, F1 symmetry switches, Fuzz 1 Depth, Gain 3, Fuzz 2 enable switch, Fuzz 2 symmetry switches, Fuzz 2 Depth, Drive 3, Bass, Mid, Treble, and Volume. Frequency Range 16 Hz to 4 kHz with all controls at 50%, or 6.3 Hz to 25 kHz with all controls at 100%. Suitable for 6/7/8-string guitar or 4/5/6-string bass. Maximum gain = +38.8 dBV @ 100 Hz with all controls at 50%, or +84.7 dBV @ 63 Hz with all controls at 100%. Power-supply not shown. Requires a regulated dual-polarity DC supply providing: +-9VDC or +-12VDC or +-15VDC at >= 60 mA of current. And though simulator verified, treat the circuit as experimental. Breadboard test it before committing to a soldered build.
