The Jewel Concert Series Tenor Sax mouthpiece is made from 100% pure hard rubber and hand worked at all critical points for exceptional playing response. Each mouthpiece is adjusted at the walls, tip rails, and baffle for exact measurements and playing response. Jewel designed the Concert Tenor mouthpiece with a very large chamber. This chamber size intensifies the richness and depth of the Tenor sound. Available in one med facing the Concert Tenor is a great choice for classical work and light jazz requiring little or no edge. The streamline style is more comfortable on the embouchure for younger players.
