I have a 1996 MIM jazz bass (the only bass I have ever owned, and the best one I have ever seen-I live in a small town) and I've got some extra money and a new band and I'd love to do some modding on it. Problem is, I really don't know any bassists in real life, and as every other bass I've ever seen has been a squier or worse, and I have no experience with this sort of thing. So, I'm asking you guys a few questions: 1. I already had my truss rod fixed, should I expect any future issues? 2. What kind of pickups should I be looking at to replace mine? 3. What things (Other than the pickups) should I be looking at upgrading? 4. What other work should I get done (like a fret job... I have no idea what that is)? 5. Is there anything else important I should know about before I do this? 6. I assume this question has already been asked, is there another thread or website you could direct me to? I've been playing for 4 years now. It's weird to realize how little I really know.
