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.

Roger Mayer Voodoo-Bass

Got a request for this one. It's the bass version of the Voodoo distortion. It's a very popular bass effect, especially in Japan apparently, but also sounds great with guitar too. A transistor stage at the input pushes a Rat-like LM308 distortion section, followed by a Big Muff-style tone stack and a simple output buffer. Here's the schematic.
