Bach mouthpieces are among the finest in the world, and the 35022GP is a brilliant manifestation of that tradition. The gold plating is preferred by many players for a variety of reasons, from feel, to appearance, to allergen considerations. A carefully selected Bach mouthpiece can help improve a trombone player's embouchure, attack, tonguing and endurance. 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 parts today. "Choosing the perfect mouthpiece is often more difficult than choosing the perfect instrument. Your success as a musician depends on the choice of equipment that will do justice to your capabilities." -Vincent Bach
