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.

Boot-Leg Effectors Rock 'n Roll Party

Here's a very nice sounding British-style overdrive pedal from Boot-Leg Effects in Japan. It uses three-quarters of a TL074 quad op-amp, as well as germanium diodes (most likely 1N60s). Original units use an electrolytic 470n capacitor, but I've laid out the board for a film cap (though the PCB has pads for an electrolytic). I've also added a pull down resistor at the input and some extra power filtering. Here's a demo from another DIY builder.
