thats close to what i do, only my pickups are right next to each other. i MAKE myself heard in the mix. they know i have wild tone and they love it.
ive got a piece of blue tape on the bridge volume knob with a line. when the line is straight up, im happy with the sound.
i know its some weird phase relationship, because the second they are uneven, i get clear tone. same with jazz basses really.
so yea, with that bass, sounds like you found the phase sweet spot, and thats a good feeling. throw another P, or maybe even a big mudbucker in the neck and you've got nearly unlimited sounds (with a few switches of course). but thats my mad scientist speaking.
