i have a 3T sunburst SX Jazz bass. i had the idea to put a MM pup (or similar) in the bridge postion. its currently passive, but thought about doing active as well. this is an advanced project for me, but im pretty down to put in the time for it. i have luithiers locally that may help. anyone have comments? questions? concerns? im sure someone has done something like this, although i was unable to find links to any previous threads. EDIT: anyone document there experiences with something like this? id like to see a start to finish kind of project.
