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.

Baja Reactor

This one was requested ages ago and I got halfway through laying it out, and then promptly forgot about it. It's a power amp/speaker cabinet simulator, emulating a SLO power amp and a couple different speaker cabinets based on the value used for CX (see schematic for values). This layout follows the Rev4 schematic from the thread here on FSB.
