I am running into a bizarre situation trying to get my new 594 to intonate. With the low E and A string saddles all the way back, the fretted 12th note is still sharper than the harmonic or open string. I am using the flat/forward, sharp/back technique. Am I nuts? Is there something I am not getting here? Is it possible that PRS made a guitar that I cannot intonate? Any help or insight would be greatly appreciated.
