Hi! i was wondering if this is possible to do in a jazz bass: -Change a Vol pot with a 3 way switch, selecting either one of the pups or both. -Use a Vol pot as a general vol control, but change it for a push/pull which can change from paralel to series between both pups. -Leave the tone control I assume this can be easyly done, but maybe im missing something. Also, since ill be changing nearly all the electronics, what would be the difference between pots with different resistance? (volume AND ton) Thanks for any info or any other input on how i can make a passive bass more versatile.
