Matt, at World of Ukes does a much better job of describing and playing my instruments than I do, so please, click on the first link below for more pictures and a description by him, the second link for a short sound demo by him, and the third link is a video demo comparing the sounds of this instrument, #177, which is X braced and #178, which is fan braced, also by him.
