300 Cornet Mouthpieces$150

The "300" Series was Developed specifically with the student in mind (although many professionals use them as well). These mouthpieces offer the same rim (similar to a 3C*) on 15 different cup depths, graduated at .006 in. intervals, (the equivalent to the thickness of two human hairs.), from deepest (No.301) to shallowest (No.315), allowing the developing player to find optimal response from a mouthpiece to perfectly match their needs.

As players mature, their needs change and mature as well. The 300 series has created a superior selection of cup depth, while maintaining the exact rim dimensions. The result is a mouthpiece that both feels good to the player and provides the desired sound instantly, without a frustrating transition.

The 300 series comes standard with our "S" (symphonic) back bore combined with a No. 27 venturri/throat. These modifications allow the players to create a richer, darker tone perfectly suited for concert bands and orchestras.


*Custom mouthpieces available upon request.
