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.

Death by Audio Soundwave Breakdown 2

Last week for Fuzz Friday I posted the early version of the Soundwave Breakdown from Death by Audio. Here's the newer version of DBA's Soundwave Breakdown with 6 transistors and another external control. On earlier examples of this revision the Sensitivity pot is an internal trimmer, but the newest version seems to have moved it externally. Speaking of trimmers, this one still has the Volume control as a trimmer (50k) and the other trimmer (5k) biases Q6. Originals are in a 1590BB, but I've laid it out to fit in a 1590B with board mounted pots. Drilling template can be found here and the schematic can be found here.
