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.

Jon Patton's Clipper Ship
Jon has contributed a lot to the DIY pedal building community and I always learn something new when I layout one of his circuits. So I think we'll have a Jon Patton week, starting with the Clipper Ship. There's a good bit of flexibility with this one. Q1 can be pretty much any low gain transistor, germanium or silicon. If you're using a germanium transistor, use a germanium diode for D2 (if you're using a silicon transistor, omit D2). For D3-4 use anything with a low clipping threshold–1N60, 1N34, BAT41, etc. Q2-3 form a cascaded JFET stage (much like the AMZ Mini-Booster and a ton of other designs). Way more info on the circuit can be found here, including the schematic. I've laid it out for a typical 1590B with board mounted pots.
