This is a very cool, metal Beechler Custom series mouthpiece for the tenor sax. This piece is stamped an 8 and measures true at .110”, with serial number 6009. This piece is in mint original condition with only very light cosmetic scratching around its body. There are no marks on the black bite plate, and the tip and rails are perfect. This piece features a long window with straight, tight side rails and a medium chamber. It plays with a strong, focused sound. A very neat mouthpiece.
