I am trying to intonate a Faber compensated hard tail bridge. I have put a fresh set of strings on and have stretched them. The neck is set up correctly and the action is adjusted. The bridge is as far forward as it can go on the studs. Currently it is flat at the 12th fret when fretted in the playing position. The open and 12th fret harmonic are in tune. As stated, I cannot move the bridge any further forward to correct the intonation. What can I do to adjust the bridge properly? I have the exact same bridge on the exact same model guitar and it is perfectly intonated.
