Interesting, but I think Morante was not talking about top resonounce, rather the actual intonation of the strings. If the guitar plays out of tune (I assume the main issue he had), then the "harmonic" test reveals exactly what is wrong (sharp or flat fretted note vs open harmonic). Most often I use this test to reveal BAD STRING SETS, but it can be a rare mistake in the geomotry as well. I assume that Morante did try different string sets before returning to cordoba. Also this exercise can show the issues with Compensation (remember Reyes doesn't use it so finger pressure can pull the note sharp if not careful) that we discussed in the past. Ricardo I'm sorry I didn't make it clear enough for you. Sometimes a different guitar design will need a different compensation, harmonically. If Reyes adjusted his designs, enough, then there might have been a need to adjust the playing scale, not just keep it at 655 mm. In other words, I can't use a 655 mm playing scale for a Rodriguez design without adding compensation, as Reyes does not do with his design. And this is going to take me some thought about using the 655 mm scale on this Conde tutorial, without having to add compensation. Also, on the Reyes style guitar, I glue the bridge about 1 mm longer, which allows for the bridge saddle to pull forward under string tension, with age, and this works for the string being pressed down when playing the guitar. So, you can't just glue the bridge at exactly 655 mm and expect it to work. At least, not on this particular 2003 design I work with. And to think about it, there might have been enough wood behind the saddle slot to move the scale longer, which might have produced a good guitar.
