when I got my RG2228A the intonation of the 8th string (F) was way off (12th fret fretted sharp compared to 12th fret harmonic).
I just tried to adjust the intonation by moving the saddle of the 8th string back, and the intonation did get better, but it's still not 100%, but the saddle is already almost all the way back (only about 1mm room left for moving it back).
Is this normal for the 8th string to not be 100% in correct intonation? Or what can I do to adjust the intonation when the saddle is already all the way to the back but the 12th fret fretted note is still sharp compared to the 12th fret harmonic?
This is how far back I got the saddle on the 8th already, while intonation is still a bit off.
As you can see the saddle is already all the way back:
I currently have a 74 on mine that won't intonate properly the entire way, i'm gonna try a 65 on there and see if it makes a difference in intonation. I'll let you know
