RS-Timbre "MOSFET Fuzz 6" PUBLIC

Shunt-MOSFET Fuzz Circuit with 3-Band Tone

Shunt-MOSFET fuzz circuit with 3-band Fender-style tone-stack. Uses one dual JFET-input op-amp IC and two dual enhancement-mode MOSFET ICs, together with Schottky diodes, in a shunt-type hard-clipping array for generating fuzz. The Fender-style tone-stack is also a modified version of that type of tone-control. Controls Include: Input Trim, Input Gain, Drive, Fuzz enable switch, Fuzz Tone, Fuzz symmetry switches, Fuzz Depth, High Trim, Low Trim, Bass, Mid, Treble, Stack Sum, Output Gain, and Volume. Frequency Range at or above 0 dBV is from 25 Hz to 25 kHz with all controls at 50%. Suitable for 6/7/8-string guitar or 4/5/6-string bass. Modest gain. Maximum Gain = +12dBV @ 1.6 kHz with all controls at 50%, and only twice that with all controls at 100%. Can be used for stomp-box or rackmount projects. The battery can be replaced by a regulated single-polarity +9V DC supply providing >= 40 mA of current. And though simulator verified, treat the circuit as experimental. Breadboard test before committing to a soldered build.
