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.

The Drivestortion Project

I really enjoyed making the Big Muff Project file a couple months ago and thought it would be fun to make a similar project based on the MXR Distortion +/DOD OD250 circuit (in an attempt to combine the 2 names I call this project the Drivestortion). This circuit was also cloned by other pedal manufacturers (apparently this was the Timmy of the 70s), so the project provides component values for a couple of these as well. Let's start with the schematic:


This is the basic circuit for several versions of the DOD OD250, the MXR Distortion +, the Ross Distortion, and the DeArmond Square Wave, just to name a few. The only difference between all these is differing component values (and sometimes not even that). The component names from the above schematic follow those in the layout drawing below.


For a full BOM for 6 different versions of this circuit, download the linked file below. In addition to the BOM, it contains scaled transfers for etching your own circuit board and a scaled drilling template for building the effect into a Hammond 1590B enclosure.

    Cool! I'm gonna build this soon (I hope).

    I have had an ongoing love affair with the MXR d+ for a few decades, I've got several dead ones I'd like to resurrect. This seems like it's 90% the first black letter variant. What version is closest to that 80's version? Thanks

    Old post I know but just built the grey DOD 250 of this project. Verified as sounding completely BADASS. Thank you.

    It adds a beautiful color, made the grey version, im just not getting enough drive even after max gain, so decided to reduce the r6, overall wonderful, thank you so much!

    Great multi-purpose post, thanks! Which version do you prefer for bass guitar?
