Alto CLassic as well as Jazz mouthpieces (6, 6*, 7, 7*) are available in Heaven material.
What is the difference between the Heaven mouthpieces and the black ones?
Our heaven mouthpieces are made from a specialized acrylic compound with metal particles embedded in the material. Combined with the metal ring at the bottom, they have a quicker, easier response, a fuller sound, and more of an edge.
The black mouthpieces tend to sound a little more mellow. Which one is “better” really comes down to personal preference and the music the player prefers.
