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.

EWS Bass Mids Control
Here's another one for the bass players. It's a pretty handy EQ pedal from EWS. Originals come in a 1590a, and sadly I wasn't able to duplicate that here, but it will fit fine in a 1590B with board mounted pots. Originals have the Volume control as an internal trimmer, but I've moved that to a full sized pot for more control (and a newer version of this pedal has all 3 control externally as well, so maybe I'm on to something haha). Here's the schematic for reference.
