On my guitar, I have it tuned perfectly open and on the 12 fret harmonic for every string. When I look at the 5th (4th for G) frets, they all read on my digital tuner as way too sharp. Could this be because of worn down frets or a warped neck?
or the bridge could need adjusting, does the neck looked warped?
The neck looks within what I would consider "normal" based on what I've read. I was playing around with the bridge saddles to get the intonation right at the 12th frets, if that's what you mean.
