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.

Fulltone 2B

 Happy 2022, everyone! Here's a buffer/booster from Fulltone. Engaged it's a booster with an interesting controllable germanium soft clipping setup, and when bypassed the diodes and gain control are shorted, creating a buffer. If you're just after the boost and want to skip the buffered bypass, just ignore the two Bypass pads and wire it normally. The original uses a 3PDT still for bypass, but you should be able to get away with a DPDT (just wire the bypass pads to lugs 1 and 2 of a DPDT, LED- to lug 4 and lug 5 to ground). Discussion and schematic over on FSB.
