Hi all, I've had my P-bass for nearly 25 years now, owned from new, and I'm wondering how worn frets need to be to require any attention. Below are a couple of shots of the first fret, but I'm not sure if this is OK to keep playing (I've not noticed any issues) or if a fret dress might be worthwhile at some point, or if it's actually worn to the point of needing replacement. Any thoughts?
