This is a vintage hard rubber Meyer mouthpiece for the alto sax. This is a “New York USA” vintage piece, originally a 5M but recently opened by Brian Powell to .082”. It has the medium chamber. This piece is in outstanding shape physically, has only a couple scratches right on top of its body from a previous ligature. There is really no other wear of note. Powell’s work on the tip and rails is incredible, and this is a monster player with a powerful, “lead alto” kind of sound.
