OK I changed to 9-40 NYXL Balanced Tension strings. I can not get this thing to intonate. A C barr chord up on the 8th fret sounds terrible. The Low E(6) saddle is all the way back and still Several Cents sharp. Neck looks to be pretty straight via looking by eye. I lowered the bridge slightly because the action was just too high. Process: Tune to pitch> Fret at 12 fret Using Korg Black Tuner/pedal and also Headstock tuner give the same readings. Any ideas?
