The Bach 50BO bass trombone provides musicians with a warm, resonant tone perfect for any ensemble. Its 9.5" one-piece hand-hammered bell offers outstanding projection and clarity. The .562" bore and open-wrap F attachment reduce air resistance for smoother playability. You'll achieve a quick handslide thanks to the chrome-plated nickel silver inner tubes. Whether you're performing a symphony or jazz solo, the 50BO bass trombone's lacquered brass construction and balanced weight make it ideal for any style.
