Experimental Op-Amp Distortion Circuit for Electric Guitar

Experimental op-amp distortion circuit for electric guitar. Uses four different dual op-amp ICs to get four different voices; one clean and three distorted. Controls Include: Input Gain, Clean Send, Distortion Drive, JFET Attenuation, JFET Send, CMOS Attenuation, CMOS Send, BJT Attenuation, BJT Send, and Volume. No tone controls. Range at or above 0 dBV is from 40 Hz to 5.4 kHz. Ideal for 6/7-string electric guitar in standard tuning. [Not recommended for 8-string guitar or bass-guitar.] Maximum gain = +17 dBV (Vo/Vi = 7.1) @ 630 Hz, or +51 dBV (Vo/Vi = 389) with all controls at 100%. Power-supply not shown. Requires a dual-polarity DC supply providing +-9VDC or +-12VDC or +-15VDC at 50 mA of current. And while circuit is simulator verified, treat it as experimental in nature. Thoroughly breadboard test before committing to a soldered build. And house in a grounded metal enclosure.
