Thanks again, Sr. Martin and Estebanana, for continuing the conversation. I will take a look at that book, Estebanana. I have always been aware and bothered that people have been concerned with the intonation at the 12th fret while ignoring it elsewhere because it is easy to check the octaves. I am guessing that a linear progression of fret compensation from none at the zeroth fret (nut) to the 19th fret, with the value at the 12th fret corresponding to the usual saddle compensation, would be effective, or interesting. Why wouldn't it be linear? So if the usual saddle compensation is, say, 1.0 mm, then the compensation at each fret is given by C = mF, where C is the compensation for the fret F; m is the slope of the line, in this case 1/12 (that is, one mm divided by the fret number 12, since the compensation at that fret is 1.0 mm); and F is the fret number. Thus the compensation, to be subtracted from the distance between the nut and fret is: Fret , Compensation 1 , 1/12 = 0.08 mm 2 , 2/12 = 0.17 mm 3 , 3/12 = 0.25 mm etc.
