Bach 42BO Stradivarius Tenor Trombone Overview
The Bach 42BO Stradivarius is an established professional large-bore tenor trombone from a model family long respected by orchestral, concert band, and solo players. Its open-wrap F attachment distinguishes it from the traditional-wrap 42B while retaining the familiar tonal concept and low-register flexibility associated with the Bach Model 42 family.

Common Questions About the Bach 42BO
How does the Bach 42BO differ from the 42B?
The 42BO uses an open-wrap F attachment, while the 42B uses a traditional-wrap layout. The two designs accommodate different response preferences rather than representing a difference in overall quality.
What does the .547-inch bore contribute?
The .547-inch bore places the 42BO in the large-bore tenor category, supporting the broad tonal profile and carrying power commonly sought in orchestral and symphonic playing.
What does the F attachment add?
The F attachment provides alternate slide positions and extends practical access into the lower register, which is useful in orchestral, ensemble, and solo literature.
