Hello. This is my first post on these forums and this seems like a cool place. Ok, I've had my Fender Aerodyne Jazz Bass for about 8 months now. I haven't had a problem with it until about 3 weeks ago. I noticed that my E string (which is usually tuned down to d or c) keeps slipping out of the nut. I play with a pick most of the time and I play pretty hard, but I don't have this problem on any of my other basses (headstocks are angled back which creates more tension against the nut). I never had this problem until recently. I'm thinking I need a new nut, but I'm not sure. There's really not much visable wear or anything on the nut. Should I just get it filed down, or get a new one, or what? It seems as though my E and A are not angled down enough with the straight headstock as the D and G are. Anyway, does anybody have any suggestions? Thanks a lot in advance.
