Project overview

This PCB allows you to build a modified version of the Fulltone® OCD®. Most notable is a voltage doubler so you can run it at 18 volts with a standard 9V supply. This has the effect of being tighter with more clarity and most people prefer it with the higher voltage. It also includes a switch to change the response of the tone control as well as a clipping diode switch.
