Each Artisan Bb trumpet is made with a one-piece hand-hammered yellow brass bell with a flat rim and special acoustic treatment in both material and manufacturing process resulting in a beautiful Bach Stradivarius sound with a larger core and a broader range of color. The two-piece valve construction with nickel balusters and brass casings harkens back to the construction techniques used by Vincent Bach when making classic Bach trumpets in New York City and Mount Vernon, New York. Monel pistons along with two sets of brass and plastic valve guides offer the player a choice in response and feel. The 3rd valve tone enhancing ring offers yet another choice in response. The extended 3rd slide rod stop allows the player to extend the range to low F. The 1st slide split ring, enhanced radius ferrules, sculpted bracing, and artistic engraving are all key contributors to the unique response while providing an unparalleled elegance in appearance. The clear lacquer finish of the AB190 provides a subtle warmth to the overall sound. These features combined with a .459" medium-large bore allow the player to produce a spectacular sound well suited for all types of music.
