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.

Dunlop Fuzz Face - Eric Johnson
Here's a layout for the Eric Johnson Fuzz Face. Had someone ask if they could build it on the basic Fuzz Face layout from last year. Since there's a few extra components in the EJ version, I thought I'd make a specific layout for it. Should still fit in a 1590a though. Q1 is a BC183 (hfe ~250), and Q2 is a BC183C (hfe ~650). Use the trimmer to bias Q2 to 3v.
