I looked everywhere for a solution and I nothing is helping, I looked if I could find something on this site but nothing. I got my Dean Dime-O-Flange in C standard and when I come to intonating the 3rd (D#) and 4th (A#) string they are always too sharp and no matter what I do they don't seem to budge. I'm using a Boss TU80 tuner and the guitar has two seymour duncan pick ups built in, hope this extra info might help.
