Ebay item #7385151853 (sorry, can't make link work) It is a volume control for Fender amps that runs through the effects loop, acting like an attenuator. For $15 I figured what the hell, might as well try it. Anyone out there have any experience with this or similar items? I don't have the $$ to spend on a hotplate right now as "home improvement syndrome" (as dangerous as GAS) is setting in. Thanks!
