Canadian Brass Tuba Mouthpiece MB-50 - Silver Plated
 
Canadian Arnold Jacobs Heritage Bass Mouthpiece Series
 
The deep cup is engineered to provide substantial volume and depth of tone, particularly on lower middle register notes which can be critical on some instruments. As examples: notes played with the second and fourth valve where long lengths of cylindrical tubing are required. The diameter and length of the throat are optimized for good resistance, contributing to fast response and enhanced play-ability on the high register. The MB-50 combines a narrow and clearly defined rim with a deep rounded cup. This is ideal for all contrabass tubas: smooth in response and colourful in tone. The MB-50 works very well, particularly for the BBb tubas and the CC tubas, that are not too big. The MB-50 offers a unique combination and balance of desirable qualities. 
 
This mouthpiece is not a direct carry over from the PT-50. The rim is more modern, the kind professionals like, the cup-shape and weight are different as above and in particular, the back bore is completely different.
