Over a century ago, Vincent Bach trombone mouthpieces set the standard for excellence and playability.

Bach trombone mouthpieces continue that standard today through constant innovation and dedication to manufacturing brass instrument mouthpieces.  Check the Bach trombone mouthpiece chart below to see our most popular sizes. 

Because no two players have the same embouchure, what is perfect for one player may be entirely unsuitable for another. Bach produces thousands of combinations of rims, cups, and backbores so that players can find the best trombone mouthpiece for their embouchure.
