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.

Jon Patton's Snow Day Overdrive

Here's a cool design by Jon Patton (seriously though, everything he designs is pretty awesome). He was kind enough to share his work and offer a full circuit explanation over on DIYSB and Madbean's forum too. Check out the thread here or here for his schematic and other goodies.


  1. hi, can you post it but without the LT?
    in my town it's unfindable :?

    1. If you don't want the charge pump, just jumper the 2 1N5817 diodes just below the LT1054, and omit the LT, 12v zenner, and the10µF cap to the right of the LT.
