The Traditional M30 is part of the industry-standard clarinet-mouthpiece range from Vandoren, and has a traditional beak design.
The difference between Traditional and Profile 88 mouthpieces is in the exterior angle of the beak. The musician is free to choose the model which suits his or her purpose in terms of best playing position, easiest sound projection, greatest playing comfort, and the most controllable and precise articulation.
The facing length of the M30 gives it great flexibility, and it has a good balance between timbre and roundness. It has a 115 (1/100 mm) tip opening and a long facing length.
