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.

Fredric Effects Unpleasant Companion

While we're on the subject of the Companion Fuzz, here's an adaption by British pedal company Fredric Effects. It replaces the fixed tone stack of the original FY-2 with a Big Muff tone stack, and adds a LPB-1 booster after the volume pot to increase the volume.

    1. Have you boxed it? If not it could just need to be shielded in an enclosure.
