Bach 42BO Stradivarius Tenor Trombone

The Bach 42BO Stradivarius is a professional Bb/F tenor trombone built around the classic 8.5-inch one-piece hand-hammered yellow brass bell that has defined the symphonic trombone sound for generations. With its .547 large bore and traditional wrap F attachment, it delivers clear articulation, confident projection, and a responsive feel with the right amount of resistance. The chrome-plated nickel silver inner slide tubes provide a consistently smooth, quick slide action suited to demanding repertoire. Finished in clear lacquer, the 42BO offers a subtly warm tonal edge that works equally well for symphonic section playing and featured solo work.

Players choose the 42BO for its dependable core and blend, while still offering the headroom needed for broad dynamics and long phrases. The traditional wrap rotary F attachment supports clean, stable response in the low register without sacrificing center in the open horn. Hand-hammered bell craftsmanship contributes to a colorful overtone profile that carries in the hall and records with clarity. This instrument’s large-bore design supports efficient airflow and a clear, projecting front to the sound—ideal for orchestral literature, brass ensemble, and solo performance. A strong fit for advanced students, conservatory players, working professionals, and doubling low-brass artists who want the long-established Bach 42BO symphonic voice.
