Ok, so I have two basses, a MIM Jazz and a Squire P, and I've been considering some improvements. As of right now I've already replaced the tuners and bridge on the Squire (stock were crap) and went over all the wiring in order to make it Fender stock (the original wiring was atrocious). The Jazz, on the other hand, is basically stock. I'm thinking that the next step in improving my axes will be to replace the pickups. I was thinking about the seymour duncan quarter pounder for the p's pickup, but don't really know about my jazz. Any suggestions on jazz setup or quarter pounds in a p-bass? I'd really like the jazz to be a good slap starter and the p-bass to be the same all around trainer it's always been, just with better sound quality. Thanks ahead of time for the feedback!
