Bach Stradivarius trumpets are the number one selling professional trumpets in the world. The 19043 features a professional #43 bell with a side-seam resulting in a quick response and a brilliant tone. The combination of two-piece valve construction, nickel silver outer slides, brass valve guides, and a steel bell wire provides a broad sound with a quick response and great feedback to the player. The clear lacquer finish provides a subtle warmth to the overall sound. These features combined with a .459 in. medium-large bore allow the player to produce a well-rounded sound well suited for all types of music.
