What's your opinion on the utility of a "compound radius" fretboard? For those of you who use them, what's you preferred configuration (10-16", 7.25-12", other)? For those of you who have built them, what do you think is the easiest way to do it? Personally, while I can clearly see that the actual shape of the strings on an instrument forms a cone, not a cylinder, and that the idea of a "compound radius" (really a conical section) should be quite obvious, I've never had any problems with any of my simple radius guitars. I've never owned a compound radius guitar, though, so maybe I'm missing out on something? I'm designing a line of guitars and basses, so I'm curious as to whether or not I should even bother, and futhermore, if I did, how would I do it? I've got a couple of ideas, but they seem a bit difficult to actually accomplish.
