It goes to eleven. This is a Miami, FL Dukoff Super Power Chamber alto piece in a D7 tip opening. This is what David Sanborn has famously played for many years. The tip measures .081″ and the facing is original. This includes the rare vintage plastic ligature and original cap. There is quite a bit of wear in the tooth guard area, and that could be cleaned up, but I just left it so you can do what you want with it. I would probably take off the extra tooth guard, clean it, and put a new clear vandoren one on there, and it should be good. These pieces show better workmanship than on the modern Dukoff pieces.
