Bach Tuba / Sousaphone Mouthpiece.
A carefully selected Bach mouthpiece can help improve a player's embouchure, attack, tonguing and endurance. Tuba and sousaphone players alike remark on the noticeable difference of using Bach's meticulously crafted instrument parts.
Vincent Bach was a rare combination of artist and engineer. A mechanical genius and acclaimed trumpet soloist, his instruments and mouthpieces are used today in every major studio and orchestra in the world. Bach personally designed the tools and composed the plans that continue to set the high standards for making all Bach products today.
