This is a Bach 42BOF Centennial Edition large bore tenor trombone in super mint condition, serial number 215343. The 42BOF Centennial model was introduced in 2018 to celebrate the 100th anniversary of the Vincent Bach Corporation, and was designed with input from Jay Friedman of the Chicago Symphony Orchestra. It represents one of the most refined production models in Bach’s history.
Key design features include an 8.5" yellow brass bell for a warm, resonant tone and a .547" large bore for the full, rich sound the 42 series is known for. The standard-weight 42 handslide offers excellent response and clarity, and the European-style open wrap with Meinlschmidt open flow valve provides a smooth, quiet, and exceptionally free-blowing playing experience.
This pre-owned instrument was played lightly for approximately 1.5–2 years and has received a full professional service, including a chemical bath and precision setup. It shows no dents, dings, or prior damage. The slide is smooth and fast, and the valve is quiet and airtight.
A brand-new 42BOF Centennial Edition sells for over $4,800 today, making this example an outstanding opportunity for any advanced or professional player seeking a truly exceptional Bach 42.

🤔 What makes the Centennial Edition different from a standard 42BOF?
The Centennial Edition incorporates input from Jay Friedman and features refined craftsmanship, a special Centennial engraving, and upgraded component tolerances. It retains the 42BOF’s open feel while offering more consistency, smoother valve action, and enhanced resonance compared to standard production models.
🤔 Why do professional players choose the 42BOF design?
The 42BOF uses a Meinlschmidt open flow rotor and European-style open wrap, resulting in lower resistance, quieter operation, and a more effortless response than traditional Bach rotary valves. It’s especially valued in orchestral and symphonic settings where consistency and tonal breadth are critical.
