This ebonite mouthpiece is designed to be used with softer reeds but without sacrificing the sound quality of a stronger reed. It is very similar to the B45 but with a wider tip rail, this is the flat section of the mouthpiece, which is level with the very tip of the reed. This tip rail produces a more centered and compact sound.
The facing length is medium long and the tip opening is medium.
The '13 series' was designed specifically for American clarinets using the A440 pitch but is very popular with all players.
This mouthpiece is also available as a profile 88 and traditional.
