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.

KMA Fuzzly Bear
For Fuzz Friday, here's an interesting take on the Bosstone fuzz with a few value changes, extra diodes, and a voltage sag control. Schematic and discussion here. I did add a bit of a mod to this–the resistor marked "0-10k" limits the minimum setting of the drive pot. Stock, lug 1 goes directly to ground. But IMO, it's a bit better to have that limiter there, otherwise it's just another way to mute the pedal. So adjust that to taste.
