I am rebuilding a Harmony Sovereign guitar and am replacing the Harmony style bridge with a pin type bridge. In order to get everything back in the right place I have checked the distance from nut to 12th fret (12 5/16") and the distance from 12th fret to bridge (12 5/8"). This does not calculate as the scale length from nut to bridge is 25 1/4".
Can this be correct? I played the guitar before taking it apart and heard no significant problem with intonation.
May be something going on here which is normal but I have little guitar experience.
Any thoughts or help appreciated.
