Taliesion 1: 2-Voice Hybrid Fuzz I PUBLIC

2-Voice Hybrid Fuzz Circuit 1 with 3-Band Tone

2-Voice hybrid diode + transistor fuzz circuit for guitar, with 3-band tone. Fuzz voices are from two clipping arrays with different devices; one feedback diode array with dedicated op-amp and one shunt-type BJT transistor array (using transistors 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 two different kinds of clipping devices. The fuzz voices are both meant to sound like vintage fuzz pedals, with Fuzz1 softer than Fuzz 2. 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 is from 40 Hz to 4 kHz with all controls at 50%. Suitable for 6/7-string guitar or 4-string bass. Maximum gain = +25.5 dBV @ 250 Hz with all controls at 50%, or +48.6 dBV @ 250 Hz with most 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.
