Bach 42BO Tenor Trombone Overview
The Bach 42BO Stradivarius is an established professional large-bore tenor trombone built around the centered sound, projection, and stability for which the Bach 42 platform is widely respected. Its open-wrap F attachment distinguishes the 42BO from the traditional-wrap 42B while retaining the familiar Model 42 tonal concept. This instrument is suited to players seeking a proven professional design for orchestral, wind ensemble, solo, chamber, and teaching work.

Who the 42BO 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 core and substantial projection. Its .547-inch bore supports a broad orchestral sound concept, while the open-wrap F attachment is designed to maintain a more open response through the valve register. Players accustomed to smaller-bore instruments should expect a design that rewards developed airflow and a well-supported embouchure.
Common Questions About the Bach 42BO
How does the 42BO differ from the Bach 42B?
The 42BO uses an open-wrap F attachment, while the 42B uses a traditional wrap. Both belong to the professional Model 42 family, but the open wrap is chosen by players who prefer a less compact attachment layout and a more open response through the valve register.
What playing concept does the .547-inch bore support?
The .547-inch large bore supports the broad, centered tonal profile commonly sought in orchestral, symphonic band, chamber, and advanced solo playing. It provides substantial carrying power while allowing experienced players to shape a wide dynamic range.
What does the F attachment add?
The F attachment extends practical access into the lower register and provides alternate slide positions that can improve facility in technically demanding passages. Its open-wrap layout is a defining feature of the 42BO configuration.
