A PCB for you to make a copy of the EQD White light Overdrive. The founder of EQD is a big fan of the DOD 250 overdrive (one of my favourites as well). They've produced a few versions based around the two knob classic DOD 250 with the emphasis on more flexibility [while also getting around the hassle of finding the "right" version and getting a good tone with more modern and lower noise component choices].
