I'm lookin to get some new pick-ups for my two basses. Both of them are passive. My P-bass is a fretless 4 string. I'm looking to get a really nice, warm, clean tone out of it. I detune it down to B-E-A-D a lot. I might be buying a new fretted neck for it soon, though. I'm not sure. My J-bass is a fretted 5 string. I want to get a fat tone out of this. The pick-ups on it now are total crap. The B string is way too quiet. I've looked at EMG's, but I want some suggestions. Should I convert them to active? I'm kinda clueless what to do, this is my first time modding a bass.
