Bach Stradivarius Trumpet in Bb 17043GYR



Find a Dealer


The Bach 170 series trumpet is a modern take on an original model by Vincent Bach. While the Stradivarius is well known for its iconic 1-piece trumpet bell, Bach’s original Apollo design featured a two-piece bell. Our new 170 line of professional-level instruments feature the same valve block and chassis as the world-famous 180 line of trumpets. Paired with our first ever 2-piece, 2-material bell that has been treated with the same top-secret annealing processes as our Stradivarius trumpets, the result is an instrument fit for a modern trumpet player of any style.


The 17043GYR features a two-piece 43 bell with a gold brass stem and yellow brass flare. The unique combination of materials results in a sound that offers the depth and richness associated with gold brass with the brilliance and shine of yellow brass. It is built on an ML .459” one-piece brass valve chassis, the same as our 180 line, and has a lightweight body with brass inner and outer slides, and brass Z braces. The model has been modernized with a new 6-style reversed leadpipe that offers exceptionally quick response and ease of play.
