My Jazz is currently wired vol/blend/tone, but I never, ever find myself using the volume knob. I learned on upright, so all the dynamic changes had to come from the fingers. I'm wondering if there would be anything more useful to me in a passive set up (with a Basslines humbucker in the neck). I was thinking perhaps doing the rewire as blend where the volume knob is, tone where the blend knob is, and a series/parallel switch in the last position. Does anyone have any experience with this sort of thing? Thanks a ton.
