I haven't, nor have I seen it. It's a very attractive wood, but also a very heavy one, and the grain is so deep that it would be difficult to get a traditional "guitar" finish on it. I doubt it would impart much, if any, tone to an instrument. I imagine it would be kinda like using Lucite or Lexan, tone-wise. As far as I've seen it go along those lines (with wood, anyway) has been mahogany, at least for the main body/neck. Tops, fretboards and accents, of course, have been made of a wide variety of woods.
