The Canadian Brass MB-50 is an ideal mouthpiece for BBb and CC tubas because it provides substantial volume as well as more fundamental in the sound. The response and high register is enhanced because of the size and shape of the throat. The MB-50 features a narrow and clearly defined rim that aids in flexibility and articulation. This mouthpiece uses the cup of the RT-50 but the rim of the Arnold Jacobs Heritage Tuba Mouthpiece.
Inner diameter: 33mm/1.29in
Cup: Deep, pear shaped
Rim: narrow, clearly defined inner edge
