Bach 42BO Stradivarius Tenor Trombone Overview
The Bach 42BO Stradivarius is a professional large-bore Bb/F tenor trombone based on the established Model 42 design. Its open-wrap F attachment provides a more direct path through the valve section than the traditional-wrap 42B, while retaining the centered core, projection, and substantial tonal character associated with the Bach 42 series. It is a respected choice for orchestral, wind ensemble, solo, and advanced studio playing.

Who the 42BO Stradivarius Tenor Trombone Is For
The 42BO is intended for professional players, advanced students, educators, and serious ensemble musicians who prefer a large-bore trombone with a centered, projecting sound and an open response through the F attachment. Its tonal weight and breadth suit orchestral and symphonic band literature particularly well, while its articulation and dynamic range also support solo, chamber, and studio work.
Common Questions About the Bach 42BO
How does the open-wrap F attachment affect the response?
The open-wrap layout uses fewer tight bends in the F-attachment tubing. Players generally choose this configuration for a more open and consistent response when the rotary valve is engaged.
How does the 42BO differ from the Bach 42B?
Both models share the large-bore Model 42 foundation. The 42BO uses an open-wrap F attachment, while the 42B uses a traditional wrap, giving players two different approaches to valve-section resistance and response.
What playing settings suit the Bach 42BO?
The 42BO is particularly well suited to orchestral, wind ensemble, brass choir, solo, and advanced studio work requiring a full large-bore tenor trombone sound.
