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.

Greaser Fuzz

Here's a cool little fuzz designed by Nocentelli over of FSB. It's based on the D*A*M GB-83, which is a silicon adaptation of the Tone Bender Mk. III (sans the tone control). Definitely worth building up. Here's the schematic for reference (you'll have to login to FSB to access).
