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.

DeadAstronaut Black Triangle

Got another take on the bufferless Tube Screamer. DeadAstronaut has added some extra tone shaping options for tone, gain, and clipping. Pretty versatile tones on tap from light drive into heavier territory. He's also got a PCB with board mounted pots and switches for sale on his site here if you don't feel like wiring all those toggle switches.


  1. Isnt there a 100R resistor to ground from the 470n and 220n?

    1. You're right. Now where the crap am I gonna put it? lol

    2. Fixed. Had to move where the power filter cap is in the voltage rail, but it should make any difference. Thanks for catching that, Dexter.

  2. Verified. Great sounding overdrive. Lots of tones. Thanks for correcting the first layout.
