I am currently taking an Epiphone Thunderbird bass and making it into a fretless. I have already done the neck and am working on refinishing it. But I wanted to put in all new electronics. I have decided to use DiMarzio Model J and DiMarzio Model P pickups and needed some suggestions on what pots to use that would work with those pickups. I want to use the same setup, Volume/Volume/Tone, that was originally on it. I'm pretty sure 250K. Any help would be greatly appreciated. Thanks.
