This is a nice S80 D hard rubber mouthpiece for alto saxophone by Selmer Paris. The mouthpiece has some light cosmetic wear around the outer body, this kind of wear is only cosmetic and has no effect on the way the piece plays. Its facing area of the table, tips and rails is in very good condition. The tip opening on this mouthpiece is just a hair under .075”, which makes it close to a 6 in Otto Link and Meyer standards.
Selmer mouthpieces have long been a top choice for professional alto players. This mouthpiece has a medium opened chamber with a square throat, slanted side walls and almost no baffle. The mouthpiece plays with excellent control, intonation and is on the darker side of the color spectrum.
