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.

Feisty Little One Thermal Detonator

It's Fuzz Friday! This one got traced on FSB a while ago and I finally got around to drawing it up. It's a silicon Fuzz Face with bias control, sag control, and switchable feedback loop (oscillation). I laid it out like a zVex pedal (at least in control layout) and it should fit in a 1590B, either with the circuit board flat or standing vertically in the enclosure.

And here's a wiring diagram to make the offboard wiring a little clearer.


  1. Verified. It has an excellent sound. I only made a few changes, I used a linear pot in the volume, because with the logarithmic it worked only 90% onwards. And the oscilate pot I left it fixed as trimpot, since I found an acceptable sound in a single point.
