Boston Sax Shop S Series 7 Hard Rubber Mouthpiece for Alto Saxophones

This is a very nice S Series 7 for alto saxophone by Boston Sax Shop. The piece has seen some play time in the past but is still in amazing physical condition. These pieces feature a “Horseshoe” chamber shape similar to the kind you would see in an old Selmer Soloist. They also have a notable rolled baffle below the tip rail. 

 

These are highly flexible jazz pieces made for the modern alto player. 

 

The tip opening on this mouthpiece measures .081”.
