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.

Gotten several requests for this one and for good reason. It's probably the best optical compressor design out there. This one's not for the feint of heart, and will take up most of a 1590BB enclosure. 3 jumpers, but the pots are board mounted. The on/off indicator LED in the original is a bi-color LED that pulsates with the signal. The switches in the original are internal, but can be mounted externally for more control. Be sure to jump lugs 3 and 5 on the EQ switch. Here's the schematic for reference.
