Bach Megatone 7C Trumpet Mouthpiece When selecting a mouthpiece, a brass instrumentalist should choose one with a solid, compact tone of large volume. A carefully selected Bach mouthpiece can help improve a player’s embouchure, attack, tonguing and endurance. Because no two players have the same lip or tooth formation, what is perfect for one may be entirely unsuitable for the other. Bach produces many different models so that each player can find the best mouthpiece for their individual embouchure. Bach Megatone 7C mouthpiece is probably the most widely use model in the world. Its brilliant tone is preferred by school musicians and artists. Features: • Cup Size: 7c • Depth of Cup: Medium • Approx.
