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.

CMAT Mods Butah

Here's a Blues Breaker variation from CMAT Mods. Seems to be a blend of the original and second versions of the Blues Breaker. Originals use a 1N4148 for polarity protection, but a 1N5817 would be better. It's laid out for board mounted pots and will fit in a 1590G if you're into those.


  1. Guess its time to start etching, Too much fun waiting to be had!!! Thank you for the great layouts.

  2. Checked! Powered by 100%. + Did modes on diodes 5mm. Thank you!
