This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Durham Crazy Horse
For Fuzz Friday here's an really interesting circuit from Durham that's both an overdrive and a fuzz. As the name implies helps you get some Neil Young tones, but does a lot more than that. The input stage features soft clipping in the feedback loop of an opamp, much like a Tube Screamer. The 2nd half of the opamp acts like a buffer, pushing a Fuzz Face-style stage. This then pushes another Fuzz Face-style stage that feeds into a Big Muff tone stack. The addition of the Volts control to starve the opamp of voltage makes this a really versatile pedal. I've laid this out with on board pots that will ideally fit in a 125B with top mounted jacks. Here's the schematic for reference.
