I have a guitar that has an odd intonation issue that is the opposite problem people usually have. On one string, all the fretted notes are flat compared to the open note. This is an acoustic guitar and it’s the G string.
The guitar came with a graphtech tusq compensated saddle that was overly compensated on a few strings (they also had flat intonation) so the other day I shaped a new saddle myself to shorten the scale length on these strings. This improved the intonation for all but that one string, which I find baffling.
The thing is, if I use a capo and eliminate the open note, the intonation is acceptable, i.e. the 1st fret note is not too off from the 13th. What could cause an open note to be sharp if the intonation otherwise checks out?
