Bach 42 Series trombones have been delivering their signature sound for generations. This 42A Stradivarius Professional Trombone features all of the classic design elements with a cutting-edge Hagmann valve. Unlike traditional valve designs, the Hagmann rotary valve preserves your wind column by diverting air at a softer angle. Bach’s team constructed this professional symphonic trombone from yellow brass for a timeless tone with generous treble detail. It has an open-wrap F attachment for alternate positions, a more comprehensive range of low tones, and more efficient slide work options during complex passages. Other premium features include a 1-piece, hand-hammered yellow brass bell for hall-filling projection, along with a larger bore for easier blowing. Here at Sweetwater, we think of the 42A Stradivarius Professional Trombone as a sonic paintbrush ? just pick it up and apply it to your musical canvas for amazingly expressive results.

Hagmann valve for ultra-smooth airflow





The F attachment is a vital component that contributes to a trombone’s overall tone. While most manufacturers offer open-wrap attachment options, few consider the tonal impact of the rotary valve. For a natural sound and playing feel, Bach equipped the 42A with a Hagmann valve. This game-changing rotor valve diverts air at a maximum angle of 60 degrees, a massive improvement over a traditional valve, which can divert air more than 90 degrees. By lessening how much air is diverted, a Hagmann valve preserves your air column and delivers a much more natural sound.





1-piece, hand-hammered bell





Bach fitted the 42A with a 1-piece bell made of yellow brass. It flares out to an impressive 8.5 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. The most skilled trombonists here at Sweetwater can even make their yellow brass horns sound brighter or darker to perfectly fit into any arrangement. For robust low end and clear highs, you can count on your 42A 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 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.
