Okay first off I want to upgrade my Fender 60's Jazz bass to the EMG JV vintage set because a)it will cut in better with a pedalboard, and b) I want to keep it "vintage". Any of you guys know about this? Thanks. Also I have my Fender P-Bass that I have questions. Here is the situation. I have installed an EMG P in my bass but A) How much work is it to make a cavity in the bridge position for a long jazz bass pickup for EMG LJ pickup and a deep dish input? B)How do I wire the P-pickup>to the J-pickup>to the EMG-BTC (stacked bass/treble cut and boost)>Input? Thanks!
