Bach 42A Stradivarius Tenor Trombone Overview

The Bach 42A Stradivarius is a professional large-bore tenor trombone built around the established Model 42 design, a series long respected by orchestral, wind ensemble, and solo players. This configuration combines the familiar Bach tonal concept with an open-wrap F attachment and Hagmann valve, giving musicians an alternative to the traditional rotary-valve Model 42 while retaining the centered character and projection associated with the Stradivarius line.

Who the 42A Stradivarius Tenor Trombone Is For

The 42A is intended for professional players, advanced students, and teachers seeking a large-bore symphonic tenor with a centered tonal core, strong projection, and an open-wrap Hagmann F-attachment system. It is particularly well suited to orchestral, wind ensemble, chamber, solo, and conservatory work where a substantial sound and dependable F-register access are priorities.

Common Questions About the Bach 42A

How does the Hagmann valve differ from a traditional rotary valve?

The Hagmann system uses a different internal airflow path than a conventional rotor. Many players select this configuration for its open response and continuity when moving between the open instrument and the F attachment.

How does the 42A fit within the Bach Model 42 family?

The 42A retains the professional .547-inch large-bore and 8.5-inch yellow-brass bell concept of the Model 42 family while adding an open-wrap Hagmann valve section. It is designed for players who prefer that valve architecture over Bach configurations equipped with a conventional rotor.

What musical settings suit the Bach 42A?

The 42A is most closely associated with orchestral and symphonic playing, but its focused projection and broad dynamic range also support wind ensemble, chamber, solo, teaching, and audition use.
