Just thought I’d get the ball rolling in the Luthier’s corner…
Elevated fingerboard are supposed to make access to the upper frets easier. I think the general consensus is that a cutaway is more effective in this regard, but there tends to be a lot of resistance to cutaways among “serious” classical guitar players. If you make guitars using the traditional Spanish construction method, elevated fingerboards are a bit tricky. When I finally got round to making one a few years ago, I decided to go with a different construction method, closer to that used for steel string guitars, where the body and neck are constructed separately, and attached near the end of the build.
Anyway, as a picture is worth a thousand words, here’s 6,000 words-worth!
