I'm rewinding some old Univox Hi-fliyer pickups that I have and I was interested in converting one (or maybe both) of them to dual coils and I was wondering... how many times is each coil wound on a passive Precision bass pickup? And a Jazz (Dual or Single)? I'm trying to achieve a warmer, fatter tone in the neck pickup and a tighter, punchier tone in the bridge pickup (similar to a pj bass) Do you guys have any tips?
