Professional Performance and Inspiring Heritage

The Bach Stradivarius 42 is a cornerstone of professional trombone performance. Designed for serious symphonic and solo players, it set a new standard with its rich, open sound and precision engineering. The 42BO model spec, with its open-wrap F attachment, continues this legacy today — handcrafted in Elkhart, Indiana with the same uncompromising quality. Renowned for its versatility and power, the 42 remains the professional’s choice for expressive, world-class performance.

Playability

The Bach 42BO is designed to be as expressive as the player behind it. With its open wrap F attachment and large bore, it offers a free-blowing experience that feels effortless, even in the most demanding passages. The hand-hammered bell responds dynamically to a player’s style, offering warm lows, clear highs, and a rich core tone — perfect for orchestral, solo, or commercial playing. Whether you’re in a concert hall or pit orchestra, the 42BO adapts seamlessly. It’s a true musical "paintbrush," capable of delivering color, power, and finesse at the player’s command.
