Bore Size 0.330 (in) Bore Size 8.38 (mm) Cup Depth - Medium Deep
Designed for Chris Hall, principal tuba with the New York Metropolitan Opera, this mouthpiece is well-focused and colorful. The CJH cb M (contrabass medium) has a medium large cup, best suited for CC and BBb tubas playing in Orchestra and Band. The size of the cup along with the variable backbores allows this mouthpiece to also work well in chamber and solo settings as well as on Eb/F tubas. As per Chris Hall's request, we offer this cup in both stainless steel and brass.
