Mercer and Barker mouthpieces are produced from the tradition of precise British engineering and fine craftsmanship. The Mercer and Barker MB4 Euphonium mouthpiece features a heavy weight design that provides remarkable clarity of articulation and quick response. The MB4 has the signature comfort of Mercer and Barker rims with a slightly bowl shaped cup that produces a very brilliant tone throughout all registers of the instrument.
