The Bach 50B3O inline independent double rotor bass trombone in the key of Bb/F/Gb features a 9-1/2" one-piece hand-hammered yellow brass bell that has defined the symphonic sound for generations. The .562" large bore combined with the open wrap F/Gb attachments offers outstanding clarity and projection with just less resistance.
The chrome-plated nickel silver inner handslide tubes provide the ideal surface for smooth and quick handslide action. The clear lacquer finish adds a subtle warmth to the sound overall. The Bach 50B3O professional bass trombone is ideal for both symphonic and solo performance.
