Overview
The Bach 42B has long been considered one of the benchmark large-bore tenor trombones in the American orchestral tradition. By the mid-1980s, the model had already established itself as a first-choice instrument for advancing students, university music programs, military bands, and professional performers.
This example, serial number 67599, remained highly original and retained its factory lacquer and original components. The instrument represented the traditional Bach approach to large-bore tenor trombone design, featuring a .547-inch bore, 8½-inch one-piece yellow brass bell, and standard rotary valve section.
Known for its broad sound, strong projection, and versatile response, the Bach 42B continues to be one of the most widely recognized orchestral tenor trombones ever produced.
Condition Summary
Condition was very good overall and reflected decades of careful use.
As expected for an instrument of this age, visible lacquer wear was present throughout portions of the instrument. The wear remained cosmetic in nature and did not affect structural integrity or playing performance.
Prior to documentation, the instrument received a complete shop service including chemical cleaning, slide optimization, valve inspection, and mechanical evaluation. The handslide moved properly, the rotor valve responded efficiently, and the instrument remained free from significant dents, dings, or structural concerns.
The original case accompanied the instrument and remained functional, although the handle showed wear consistent with age and use.
Player Perspective
For generations of trombonists, the Bach 42B has represented the standard American orchestral tenor trombone.
The .547-inch bore and large bell design provide the breadth, projection, and tonal depth required for symphonic literature while remaining flexible enough for wind ensemble, church orchestra, chamber music, and advanced academic settings.
Players often appreciate the centered response, strong core to the sound, and ability to project effectively while maintaining warmth and color throughout the dynamic range.
A properly functioning Bach 42B remains equally comfortable in the hands of serious students, educators, freelancers, and professional orchestral musicians.
