I have a P-Bass that I want a bit more versatility from, and want to keep passive. So I'm thinking replace the stock pickup, a J in the bridge, move the jack to the side, have a blend knob added (with center dentent), and use a series/parallel mini switch and get a Mid/Tone passive tone control from http://www.has-sound.com/. My question is what do you think about this? Also which pickups? I was thinking a Bart in the bridge and a Duncan Antiquity P. Thanks!
