Mercer and Barker mouthpieces are produced from the tradition of precise British engineering and fine craftsmanship. The Mercer and Barker MB4F Euphonium mouthpiece is primarily based on the MB4; a mouthpiece that features a heavy weight design while providing a remarkable clarity of articulation and quick response. The MB4F has a relatively flat rim that gives the player even more clarity of attack and easier flexibility. The moderate bowl shape of the cup produces a brilliant tone throughout all registers of the instrument. The MB4F is currently available in large shank models.
