From the post
For #fuzzfriday, here's the Red Fuzz, designed by Robin Tomtlund. It's made up of 2 stages: the first is based around a single op amp with LEDs is the feedback loop creating clipping. The second is a simple FET-based boost/buffer. Much like a RAT, but with different clipping. The schematic and some sound samples can be found on the General Guitar Gadgets page. On the PCB, I added 2 pads that can be used to add a clipping switch. Just use a DPDT with the LEDs on one side and 1N4148s or whatever your preference is on the other (see the diagram below).
