The Vandoren 13 Series M13 Bb Clarinet Mouthpiece offers many of the characteristics of older American mouthpieces which are so widely sought after. The M13 permits easy blowing with harder reeds and produces a rich, dark, centered sound. Response is particularly sensitive.

Vandoren has developed the '13 Series' mouthpiece specifically for American clarinetists using A440 pitch.
