Breadboarded an old 70’s era Craig Anderton Comparator fuzz

[Rambozo96]

As the title states I wanted to make use of the breadboard before committing this to a more permanent circuitboard trying to play around with distortion from an opamp set as a comparator and along the way I stumbled upon the Craig Anderton article from 1972 for the Optimum Fuzz. Seeing this design is made up of a small handful of parts I felt it would be a good thing to learn on for laying out a breadboard. Verified it worked on my oscilloscope when I saw a nice healthy amplified square wave on the end of the circuit. Tested it on the guitar and sure enough it was a wall of fuzz. Unfortunately I didn’t have any pots on hand so I had to set it up as if it had all the controls maxed out.

Just add some low-cut filtering and that's a tight sound right there

That’s why I used a breadboard. It did have a bit more bass than I’d have liked.

Cool. I assume you're going to produce a few if you're investing in a pcb.

I would like to figure out a way to make it run on a nonfloating power supply that way it’s much more pedalboard friendly. As is if you tried to daisy chain it with a non isolated power supply it won’t work. I think I know a way to do it. Just looking for an outside the box way to achieve fuzz.
