I play with a couple of bands, one of them I leave my combo in the rehearsal space to save effort, the guy who owns the space has all sorts of band gear of his own there so lately I've been playing his mid 80's -ish Squire Jazz bass. Its not very enjoyable to play but all I carry now is a mic and boom and a couple cables, so that's nice. So the other day I decided that if I was going to play it, I might as well tune it up. So I showed up early with my tools and adjusted the truss rod, action, and intonation. Wow - what a difference! It sounds better. It plays better. Actually that's not true. It sounds and plays GREAT! The round wounds on it are ancient (or as I call it, "broken it"), and I cut up some foam and inserted it under the bridge so now it has a great sound for playing with pick or fingers, at least in the genre I play (60's - current rock and soul). Lesson learned - tune up your toys, then it will be more fun when you turn up your volume!
