I have an American Strat with the vintage bridge and saddles. The G string gives off a ring noise after plucking it. Is it technically a buzz, but just sounds more like a ring, because it is a lighter gauge than the low E and A strings? I have noticed this with the G string on other guitars as well. The frets are level, the action is 4/64 (normal), and the relief is good (about 8/1000). Has anyone experienced this? And is there something to try? Add on: Some people mentioned filing the nut. I think it’s not that, because when I play it open it is fine. It is only when I play from the first fret all the way up to the 18th.
