The Bach 170 Stradivarius 43 Bell Series trumpet provides a professional-level instrument for the discerning musician. With a two-piece, 43 bell made of gold brass and yellow brass, you'll achieve a rich, brilliant tone suited for any musical style. Built on the same ML .459" one-piece brass valve chassis as Bach's renowned 180 line, this trumpet offers lightweight maneuverability and responsive valves. The two-piece bell's gold brass stem provides depth and warmth, while the yellow brass flare adds shimmer and projection. As an added benefit, the 170 Series' standard leadpipe and choice of lacquer or silver plate finish mean you can find an instrument perfectly suited to your tastes.
