I recently bought a used bass I love and have been playing a lot for the last couple months. When I got it I had done a quick setup which got it into the ballpark of what I like, and then just played and played it. Its a GREAT bass. Today I decided to start tweaking the action a little, and all of a sudden C# on the G string will not sound cleanly under normal finger pressure. If I press REALLY hard with my fretting hand, it will ring out, but otherwise it sounds like there is fabric on the string or something. Not dead ... completely choked! The note will not sound hardly at all! To answer the first questions I would have: I'm a very experienced player, and have been doing my own setups for years. I've even built a few guitars and basses, and I've NEVER seen anything like this. Usually if a fret is high or low I'll get string buzz ... this is NOT string buzz. This is also NOT a dead spot, it was working great before that truss rod tweak, and its not that it has a short decay ... I get almost nothing out of the note. I've set the action back where it was (> 2/32" @ 12th fret) and the problem presists! I tried increasing and decreasing the relif, and nothing changes it! HELP! I love this bass and this puts it completely out of commission!!!! The note is not usable. I'm baffled! The frets do show wear, but if the fret was warn wouldn't I get buzzing ... and why would a truss rod adjustment have effected it?! Is a fret loose? Did the neck just freak out and develop a bump?! I can't see anything wrong with the naked eye. I DID change strings, and it didn't change anything.
