Mercer and Barker mouthpieces are produced from the tradition of precise British engineering and fine craftsmanship. The Mercer and Barker MB1 is a large tuba mouthpiece designed to make playing throughout the range of the tuba easier. The mouthpiece rim is geared towards helping the player smoothly transition from register to register with minimal changes in the jaw position. The rim also provides the player with more comfort so that endurance is not an issue. Mercer and Barker describe the end result of the MB1 tuba mouthpiece as a warm, rich, and velvety tone that has become a popular choice for players with strong embouchures. The MB1 has also proven to be a great tool for creating a wide range of dynamics. It is currently available in both large (European) and standard (American) shanks.
