Here is a call that I finished the other day made from Bubinga from West Africa with a Maple Burl inlay. The Maple Burl was harvested from a Maple tree on a mountainside overlooking the Obey River in Clay County, Tennessee. The call is ceramic over a crystal soundboard. Crystal gives you move volume and crisper sound then a glass soundboard. The striker is made from Bubinga with a Whitetail deer antler laminated on the crown of the striker.
