Mercer and Barker mouthpieces are produced from the tradition of precise British engineering and fine craftsmanship. The Mercer and Barker MB4 tuba mouthpiece is designed for the modern tuba soloist and works very well with F and Eb tubas. The shape and depth of the cup contributes to a brighter, lively sound that projects well. The MB4 also helps the player achieve very clear articulations and improves flexibility. The rim is geared towards providing maximum comfort and endurance.
