i have a dod punkifier and a dod deathmetal both from the early 90s with the old stlye fonts. the dethmetal works 100% and the punkifier seems to work ok but has an odd volume drop problem(?) with the first knob...not sure if it's supposed to do that or not, i haven't used it in years and just checked them now. they are both missing the rear battery covers though. ummm make me an offer if you want them i guess.
