From the moment you take it out of the case, you’ll marvel at its stunning handcrafted features and detail-oriented construction. The 50BO features an expansive 0.562-inch main bore and 9.5-inch yellow brass bell for a classic symphonic sound with truckloads of tonal body.

9.5” Yellow Brass Bell





Bach fitted the 50BO with a 1-piece bell made of yellow brass. It flares out to an impressive 9.5 inches for robust projection needed in big band and pit band settings. The craftspeople at Bach hammer the bell by hand to ensure it delivers the sound that’s defined symphonic trombone for decades. Providing a cutting and resonant tone, the yellow brass also has a reputation for reacting favorably to a player’s unique style. For robust low-end and clear highs, you can count on your 50BO to get you there.





F attachment with traditional wrap





Bach's team of engineers consider the F attachment as a vital component that contributes to the overall tone ? an attitude that's not shared by some of the other major manufacturers. Bach opted for an open wrap instead of the traditional closed wrap that has a reputation for choking tone and adding resistance. The open wrap facilitates a playing experience that feels like the attachment isn’t even there. You’ll appreciate the ergonomically placed standard rotor valve and the spot-on intonation provided by the separate tuning slide.





Bach: the professional choice





Often copied but never truly imitated, Bach trombones are the choice of players worldwide. Vincent Bach founded Bach brass in 1918 after a mouthpiece repair went wrong. By 1928, Bach introduced trombones into his lineup. Bach’s famous trombone designs stemmed from a combination of his musical know-how and his engineering talent. He successfully identified what he needed from a trombone and set about creating an instrument that could solve the unique issues experienced by trombone players ? and he never looked back. More than a century later, Bach instruments are proudly crafted in Elkhart, Indiana, to the same lofty standards as those from the ’20s and ’30s.
