Mouthpiece in excellent condition, just too small for Bb Tuba in a brass band setting for me so bought a bigger model MB3 “Power” Tuba Mouthpiece with a deeper cup that our MB3 this is our most versatile tuba mouthpiece, it perfectly sits comfortable on both EEb and BBb Tubas, for those players that move across both instruments this is a marriage made in heaven. Similar in size to the Bach 24AW this has slightly more weight to enhance the sound and a very comfortable rim that aids fatigue. Specifications: Cup Diameter: 31.55mm Throat: 9.00mm Rim: 8.00mm Comparisons: Deeper than the MB3, More focussed Sound
