Ok, so I recently wired up my mess around fretless J-style bass' pickups to be out of phase. I simply swapped the neck pickup's hot and ground wires to do this. I already had a series/parallel switch on this bass, and in series mode it sounds really great, although parallel is good too. when both pickups are full up, the tone thins out a lot and loses a slight amount of output. I kinda like this tone on this fretless, especially since I'm not a big fan of the way the jazz bass pickups "scoop" the tone when both pups are full.
Wondering, do any of you do this and like the sound?

Tap the coil
maybe you should just split the coil
