Ok I searched but didn't find a sufficent answer. I have a P/J setup (both pickups are humbucking) I'm putting in 2 vol and 2 tone plus a master bass tone pot(rolls off the bass rather than the treb). I was wondering what value pots I should use? Most basses use 250k for everything. I've rarely seen anything else used on bass. Any suggestions? I play hard rock, punk, and rockabilly. I love that deep p bass sound but also need that jazz tone too.
