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.

Tres Hombres

The Tres Hombres is a distortion/fuzz designed by Marcelo Trípodi on the DIYStompboxes forum. In a nut shell, it's three similar germanium transistor stages with fuzz and volume controls. There's also a switch to add an extra capacitor at the input to fatten up the sound. Marcelo recommends 2SA101 transistors with an hFE of 50 and leakage of 150ua. Socket and experiment. The perf side of the layout below is for positive ground, and the PCB is for negative ground.

  1. I've just built npn version w MP35 on a perf board. Sounds pretty good.
