Jazz basses are the best basses for any and every possible thing. Period. If you don't have one, get one. If you can't get one, find a corner to cry in. If you don't want one, see a doctor. If he can't help, quit. You just have to deal with the fact that my bass is better than yours... unless your bass is a Jazz bass, in which case, you've made the right choice and may continue playing and enjoying a fine, well-crafted instrument. Think I'm wrong? Fight me. And proceed to lose because I have a Jazz bass and you have something that is not a Jazz bass and therefore inferior.
