Bach’s 12C small shank trombone mouthpiece is found around the world. With its medium depth cup, 24.50 millimeter diameter, and medium-wide rim, the 12C delivers a bright and cheerful sound with purposeful note definition. When they visited Sweetwater, the Bach team told us that the 12C small shank mouthpiece is their best-selling model for general use. This mouthpiece is a lovely choice for the low brass player who wears many different hats onstage. And with its gold-plated rim and cup, this version of the 12C is the perfect mouthpiece for players who are allergic to silver. Players of all stripes will enjoy the smooth, luxurious feel of the Bach 12C’s gold-plated rim.
Before designing his first instrument, Vincent “Bach” Schrotenbach created custom mouthpieces for brass players. In the ensuing decade, the Vincent Bach corporation has introduced renowned designs played around the world. Sweetwater is proud to now offer these legendary mouthpieces to the public, with a wide variety of models sporting different cup depths, diameters, and shapes to fit each player’s unique style. Whether it be a student model or an advanced design, Bach brass mouthpieces will deliver consistent results each time they’re fitted into the leadpipe. Not sure where to start?
