This ebonite mouthpiece shares many of the qualities of the B40 and blends a rich sound with rich tone colour. It is also easy blowing especially in the upper register.
This mouthpiece has a long facing length and a medium - open tip opening.
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.
