Hello, I ordered a gibson 24 3/4" scale fingerboard from StewMac and I have a question: they said that it is based on a 24 9/16" scale Gibson uses, but when I measured the distance of the frets from the nut it seems more like a 24 9/16" than a 24 3/4" scale (acording to Hiscock book's measurements, I measured the 12th, 16th and the 22th frets from the nut and it seem to be 24 9/16" not 24 3/4"), am I wrong?. I´m having trouble locating the bridge- please tell me what scale use: the 24 3/4" or the 24 9/16", thanks a lot.
