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.

Maxon released the OD808 in 1979 and it generates natural, mild overdrive tones and is similar to the TS808. Original units used MC1458P ICs, but I've listed JRC4558s as they're likely to be on hand for many of you. Also the original diodes were Panasonic MA150. I've listed 1N4148s as a replacement, but socket and experiment there. I've read of people using 1N60Ps or similar germanium diodes to give it an even more tube-like sound.
