Versatile mouthpieces, inspired by the German sound: M30D and B40D. This Boehm system model, specially adapted to the German clarinet and the "Reform Boehm", is offered in two openings: M30D and B40D. The length and diameter of the shank, the bore, the appearance of the tip rail and the external shape are the components of this new concept, which offers a perfect balance between a very warm sound and great intonation. 56 Rue Lepic reeds are more particularly recommended for these mouthpieces.
