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.

Earthquaker Devices Westwood

For the blog's 600th layout, here's a new one that didn't take long to get traced. Here's EQD's newest offering, the Westwood Translucent Drive Manipulator. Great for pushing your amp and giving a near clean boost. It features an active 2-band EQ and sounds great on bass as well as guitar.
