The Canadian Brass MB-64 Tuba mouthpiece is a tool that is ideal for the F and Eb tubas as well as solo, and chamber music. It also works very well for the higher excerpts of the orchestral repertoire. The MB-64 is primarily designed with the larger size of the modern bass tuba in consideration. It easily secures the high range but also locks in the low notes. It combines the cup of the RT-64 with the shell of the Arnold Jacobs Heritage Tuba mouthpiece.
Inner diameter: 32mm/1.26in
Rim: Slightly cushioned, with clearly defined edge
