This guy I work with who is also is a bass player says that its the wood that makkes a bass or guitar sound good not the electronics. I think its both and I want to add better pick ups to this Ibanez I have because I like the way the neck feels. I also want to upgrade the bridge to a badass and change out the tuners maybe. he says I should just trade it in fro a better bass made of better materials. I think I could improve the sound with better pick ups and bridge. Is it worth upgrading or just trading in? I am also looking for suggestions on what kind of pick ups would be good. It has a P bass and a J bass style pick up.
