I need help finding the right set of strings. I play a Jazz bass - well, sort of. It is a J bass body, but with a P neck (maple neck and board) and has two Seymour Duncan Basslines humbuckers in it (the EMG 35 sized ones, I think) it's passive and is volume-volume-tone. I need help finding a good set of strings. I currently use nickel roundwounds but I don't get enough fullness or bottom end. I need the tone to be able to get fuller/deeper and rounder, but I also need strings that are versatile. I play in several jazz bands, a punk/ska outfit and a funky/rock band. So I need to be able to get a few different sounds. EQ always helps, of course, but the strings are too huge a factor to ignore. I don't mind using flats and from what I've heard that might be the way I need to go. My two concerns are this: I need something that will sustain, so flats/other strings that don't ring very long are a no-go. Also I prefer a little bit of stiffness/tension. Doesn't have to be a lot, but don't recommend something like the TIs. They aren't tight enough.
