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.

Run Off Groove 22/7

Here's something interesting to do with some of those 4049UB chips. It's a CMOS Big Muff (22/7 being the fractional equivalent of pi). Brian from ROG added a switch to the tone stack to allow for flat response and a super scooped response, in addition to the classic scooped mids. I've also drawn up a version without that switch if you don't want to mess with the extra wiring. Schematic and sound clips can be found on the ROG project page.
