This is a vintage Selmer mouthpiece for the alto saxophone. It's a short shank "Soloist" piece with a G tip opening. This is a classic piece with a nice larger than usual opening that measures .095".
The piece is in outstanding physical condition. The bite plate has just a couple VERY SLIGHT surface scratches. The gold lettering on top of the mouthpiece is still clear and pristine. The tip, rails, and baffle are all in fantastic shape.
The sound on the piece is very open and free. It has tons of projection with a slightly spread sound. The mouthpiece also has a nice warm core to the tone. This is an absolutely incredible piece.
