So I have a Paul Allander sig model, I play in drop c and use 11-54 gauge strings. I have another prs guitar that has an identical setup and intonation is great. But on this one I tuned the open note, and fretted the 12th fret and every note is sharp. I have moved the Saddles to their max and every note is still sharp. Anyone have any advice or tips? This has been driving me crazy, I don't see what I'm missing.
