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.

Gretsch ControFuzz

For Fuzz Friday I give you the ControFuzz from Gretsch. Originals are pretty rare and it's an fairly unique design based around a single 4558 chip. I found a build report from LucifersTrip over on DIYSB, and he suggested a slight mod to the Distortion control that improves the circuit, so the layout below is based on that.
