Bach 42BOF Tenor Trombone Overview
The Bach 42BOF Stradivarius is a professional large-bore tenor trombone built on the long-established Model 42 platform. It combines the series' orchestral-oriented design with an open-wrap F attachment and Bach Open Flow rotor, giving players the familiar centered Bach concept with a distinct valve configuration. Made in Elkhart, Indiana, the 42BOF is designed for demanding ensemble, solo, and studio applications.

Condition & Setup
This Open Box instrument is in excellent playing order. It has been professionally serviced, set up, and play-tested before sale. The lacquer retains a glossy presentation, with fine scratches and light handling marks on portions of the bell throat and flare. The rotor cap and adjacent hardware show light surface scuffing, and a tiny spot of surface oxidation is visible near the rotor linkage.
Who the 42BOF Tenor Trombone Is For
The 42BOF is well suited to professional players, advanced students, and teachers seeking a substantial, centered large-bore tenor sound for orchestral, symphonic band, chamber, solo, and studio work. Its .547-inch design supports breadth and projection across a wide dynamic range, while the Open Flow rotor makes this model particularly relevant to players who use the F attachment extensively and want an alternative to the standard rotor configuration found on the 42BO.
Common Questions About the Bach 42BOF
How does the 42BOF differ from the Bach 42BO?
Both models use a .547-inch bore, an 8.5-inch yellow brass bell, and an open-wrap F attachment. The 42BOF substitutes Bach's Open Flow rotor for the standard rotor used on the 42BO, giving the two models different valve configurations and playing feel.
What playing profile does the .547-inch bore provide?
A .547-inch bore is the established large-bore format for professional symphonic tenor trombones. It supports a broad tonal core, substantial projection, and the air capacity needed for orchestral and large-ensemble playing.
Where does the 42BOF fit within the Bach trombone lineup?
The 42BOF belongs to Bach's professional Stradivarius Model 42 family. It offers the established 42 platform with an open-wrap attachment and Open Flow rotor, distinguishing it from the traditional-wrap 42B, standard-rotor 42BO, Hagmann-equipped 42A, and axial-flow 42AF.
