Product Description

Large trumpet mouthpiece for superior precision. Bach Standard Series mouthpieces are some of the most popular mouthpieces in the world among both students and professionals. They are categorized from large to small diameters numerically, and from the deepest to the shallowest cup alphabetically. Model 1 Bach Standard Series mouthpieces are the largest cup diameter, and letter A cups are the deepest. Progressively smaller diameter cups are deliniated through number 20 and shallower cup depths are deliniated through letter F. 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.
