Is there any reason a person can't mix Precision Bass pickups .. y'know a treble coil-set from one maker or type, and a bass coil-set from an other maker or type? I mean as long as you stay all passive or all active? And can you put a tone control on each coil-set? One tone control for the bass pickup and one tone control for the treble pickup? Seems like dumb questions but ya never know sometimes, I figure the worst that can happen is I'll get called a dumass. And that happens alot anyway so it's no big. Haahaa!
