Overview
The Bach 42B traditional wrap tenor trombone has long been considered one of the most important large bore trombone designs in modern brass playing. This mid-1980s example (circa 1985–1986) reflects a period of consistent production where these instruments were widely used by advancing students, serious amateurs, and professional players alike.
Featuring a .547 bore and an 8.5" yellow brass bell, the 42B delivers the broad, centered sound that defines the large bore tenor category. The traditional wrap rotor design provides a familiar playing feel with balanced resistance and reliable response.
📸 Photography From Our Early Archive
These photographs are from the early years of The Brass Exchange and reflect the evolution of our approach to instrument photography. While our current images follow a more refined studio process, these earlier photos remain an important part of our archive and documentation.
They continue to serve as a useful visual reference for players researching vintage trombones, including details such as bell shape, finish, and overall condition. Over time, our photography has developed into a more consistent, fine-art approach to capturing brass instruments, but these images represent the foundation of that process.

Questions Trombone Players Often Ask
What is the difference between traditional wrap and open wrap on a Bach 42?
Traditional wrap designs have a more compact tubing layout, which can create slightly more resistance and a more centered feel. Open wrap designs typically offer a more open airflow and freer response, but the choice often comes down to player preference.
Is the Bach 42B a good trombone for orchestral playing?
Yes. The 42B is one of the most commonly used large bore tenor trombones in orchestral and symphonic settings due to its broad sound and reliable response.
How does a 1980s Bach 42B compare to newer models?
The core design has remained consistent, but some players prefer earlier examples for their build consistency and traditional playing characteristics. Differences are often subtle and come down to individual instrument variation.
