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 1
Happy Fuzz Friday, everybody. Ranjam over on FSB traced an early DBA Soundwave Breakdown (serial number 4) which it's different than the current model. The unit he traced didn't have the trimmers later units did. Don't know the original value of those trimmers, but 50-100k is a good starting point. Those trimmers control the input signal (the left one) and the output volume (the right one). True to DBA form, this is a bit of a weird circuit with the NPN darlington transistors flipped around from usual (emitter to voltage instead of ground). Schematic can be found here. Should be able to squeeze it into a 1590a.
