Guitar is an ibanez RG350DX.
I have owned the guitar for about 5 years.
Recently, i found that the fretted note are not really staying in tune even when the open strings and innotation are tuned perfectly right.
Basically...on the low E, open string is perfect E, but when I play fret one, it is not a perfect F, it is higher, it is almost half way between F and F sharp.
Playing around with it more, I found that basically the harder I press, the higher the note. With normal fretting pressure, it is about 30% higher. If I fret it REALLY hard, it is about 60% higher (the note is closer to F sharp than to F) If i fret by barely touching, it is perfect.
This problem is more appearent in fret 1-5, and less on the higher fret.
It is probably not the strings, coz I just replaced them.
Could fret wear possibly cause this problem? (There are some degree of fretwear, the top of the fretwire is starting to get flat.
Any expereinced guitar tech know the cause of this?
