I think I've made a decision. After trying a bunch of basses and pickups for a while my favorite sound I've come across has been a Marcus Miller pickup in the bridge position. I've tried five P-bass pickups and even though a couple sounded ok, they're out. The new plan is a JB neck in the regular spot and something like this http://cgi.ebay.com/Dual-fender-jaz...ryZ85856QQssPageNameZWDVWQQrdZ1QQcmdZViewItem in the bridge spot. The main pickup, the Miller, will be closest to the bridge and the other stuff will be there to enhance it. It's weird, I got an idea of sticking two J pickups together, and then I found out it's been done.
