Bold, Versatile Bass Trombone

For many trombonists, including those at Sweetwater, versatility is the name of the trombone game. And with a Bach 50B3O Stradivarius Professional Bass Trombone slung over your shoulder, you’ll be able to climb any musical mountain. This trombone comes with pro-level appointments and oozes handcrafted magic from the moment you take it out of the case. The 50B3O has a 9.5-inch yellow brass bell and 0.562-inch main bore to produce a stunning symphonic tone with extra girth. It has a pair of attachments, pitched in F and Gb, each with independent rotors and fully mechanical linkages. The Bach 50B3O Stradivarius Professional Bass Trombone is a great choice for symphonic and brass ensembles.

If you ask us, the most exciting thing about the Bach 50B3O Stradivarius Professional Bass Trombone is the attachment configuration. It’s equipped with both F and Gb attachments, which let you deliver a growling low Bb with absolute ease. And with its independent in-line rotors, you can use each attachment individually and breeze past the limitations of traditional dependent systems. This may take some getting used to, but a whole new world of creative playing opens up for you. And as an extra cherry on top of this superb symphonic sundae, the open wrap design provides a free playing experience with very little resistance.

9.5-inch yellow brass bell

Bach fitted the 50B3O 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 50B3O to get you there.

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.
