I'm currently in the middle of building my own bass guitar. My plan is to take bits from my oldest bass (I recently bought a new one) which is a crappy Samick P bass copy. It's pickup configuration is the standard P/J (which stands for PBass/JazzBass I assume?). My question is, would the jazz pickup, which is located near the bridge, be enough on it's own if I put it in my new bass? (I.e. would it give enough output) What's the difference between the P and J pickups? Would the J pickup give a different tone? I'm planning on having just one pickup closer to the neck and I also plan to upgrade it when I get the money. Thanks.
