Bach LT42A Stradivarius Tenor Trombone Overview
The Bach Stradivarius Model 42 family is well established among professional large-bore tenor trombonists for its centered tonal concept, projection, and versatility. The LT42A configuration combines that familiar Model 42 foundation with a lightweight handslide and a Hagmann F-attachment, giving players a distinctive alternative to standard-weight slide and conventional rotary-valve configurations.

Who the LT42A Stradivarius Tenor Trombone Is For
The LT42A is suited to professional players, advanced students, and educators seeking a large-bore tenor trombone for orchestral, wind ensemble, solo, chamber, and commercial work. Its lightweight handslide favors an agile physical feel, while the Hagmann F-attachment offers a more open valve concept than the conventional rotary-valve configurations found on many Model 42 variants. Players who prefer greater slide mass or a traditional rotor response may favor another Model 42 configuration.
Common Questions About the Bach LT42A
How does the lightweight handslide affect the LT42A?
A lightweight handslide reduces moving mass and can contribute to a quicker physical response during articulation and rapid slide movement. The difference is also tactile, and some players prefer the steadier feel of a standard-weight slide.
What distinguishes the 42A configuration from the 42B and 42BO?
The 42A uses an open-wrap Hagmann F-attachment. The 42B uses a traditional-wrap standard rotor, while the 42BO combines an open wrap with a standard rotor. Each configuration offers a different valve response and playing feel.
Where does the LT42A fit within the Bach trombone line?
The LT42A belongs to Bach's professional Stradivarius large-bore tenor trombone family. It is intended for players who want the established Model 42 tonal concept with the distinct feel of a lightweight slide and Hagmann valve.
