hey guys i have an epiphone les paul standard quilt top, and checked the intonation and it was a littl off on like 4 of the six strings, how can I fix this, like is there a website explaining it for my guitar or should I take it to a shop since Im not a professional. Thanks in advance.
actually before anyone answers, when i played the 12th fret harmonic, it matched the open string, but when I fretted the 12 fret it didn't which is right?
