It just occurred to me the top on my Jazz on the arm rest part is still the top wood. Looking at it from the side most of the top wood is only fairly thin, but get to the arm rest part of the body, and its still the same. Usually builders will just sand that part, exposing the main body wood. Just wondering how he did this.? . I presume he's cut the top wood deeper on the arm rest, so as not to loose it when sanded down. ?? I hope this makes sense.
