Mercer and Barker mouthpieces are produced from the tradition of precise British engineering and fine craftsmanship. The Mercer and Barker MB3 Grezzy tuba mouthpiece gets is nickname from one of the leading tubists in the UK, Simon Gresswell. Mr. Gresswell highly endorses the MB3 because of its evenness of tone quality in all registers. The MB3 is also designed to give the player security in the high register without sacrificing the low range. The mouthpiece rim is geared towards helping the player smoothly transition from register to register with minimal changes in the jaw position. As modern solo and chamber music becomes more demanding for tuba players, the MB3 provides a valuable tool for performing this literature.
