ChedevilleUmbra Bb Clarinet Mouthpiece F4
1/3
Independent shopping perspective
The Korena take
The Umbra F4 is a Bb clarinet mouthpiece developed with Milan Rericha. Its Umbra design combines a darker sound color than Chedeville Elite with less resistance, giving players room to shape dynamics, articulation, and color without the mouthpiece adding resistance. Proprietary Chedeville Rubber—a purer rod ebonite—forms the material basis. Manufacturing takes place in Savannah, Georgia, using CNC machines and essential handwork from mouthpiece artisans.
