The Black Diamond ebonite mouthpiece features a new internal and external design. These developments offer the musician a full sound, rich in depth and colour, especially in the upper register of the clarinet. The Bb Black Diamond mouthpiece is also available in 13 Series (American pitch).
The BD5 offers the perfect balance between a dark, rich, yet compact sound. It has a 113 (1/100 mm) tip opening and a medium facing length.
