Gibson Grabber Reissue,,,G3 E string intonation
I put new GHS flats, light guage on, tweaked the neck, plays great.
Problem: can't get the e string intonated. It's flat when fretted at the 12th fret. The setting screw is backed full out, and I'm 15-18 cents (is that right word?) flat. Other strings are just great.
Any ideas about what's going on and how to fix?
