While some Dean guitars are just great, we have seen more of them with the bridge saddles in the wrong position than with other similar instruments. I think these guitars come from Samick, as do 10 other brands, so we have been puzzled as to this situation. It wouldn't hurt to measure from inside the top nut to the 12th fret, then from the 12th fret to the bridge saddle, just to be sure. Or have the dealer slap on a new set of strings so you can check intonation at the 12th fret. Using an electronic tuner you should get a true octave.
