The new 19072X is a result of testing with our top artists to create a trumpet with the hallmark Bach sound and the sizzle that commercial players love. The lightweight nickel inner slides and nickel balusters keep the sound from breaking up, even at extreme dynamics and our true French bead bell offers unparalleled projection. It also has some of our most iconic features from our best vintage instruments, including Mount Vernon-style bell construction, New York-style cast nickel Z braces, and adding a modern and consistently precise leadpipe.Bach's Research & Development team examined the most famous horns in Bach's history to identify the optimal weight, construction, material, and assembly of Bach's valve cluster. As a result of our efforts, we have produced a newly designed valve cluster delivering a faster response and a more vibrant sound. Nothing beats the sound of Bach.
