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.

Krank Distortus Maximus

This was a request. It's another 386-based distortion, similar in theory to the DAM Sonic Titan. Transistor-based "preamp" section which is amplified by the 386 "power" section, follwed by a 3-band tone stage on the output.

    3. I had forgotten to tell, some resistors were replaced. I used 39k in 43K, and 430K I used 390k. This could be the problem?

    1. Finally found a schematic of it, and while it's really close, the tone section is a bit different. So this layout won't work for it. I'll add it to the list though.
