The DOD Overdrive 250 distortion pedal is very similar to the MXR Distortion Plus pedal. This project uses the same Ready-For-Transfer Printed Circuit Board Layout file that is used in the MXR Distortion Plus Project on this site. This is really a great sounding distortion pedal, remenisent of some of the great sounds of the 1970’s. In our option, the 741 IC or similar, is essential to the great sound.
