For some players, the resistance of a standard rotor valve can inhibit their performance. If you fall into that camp, you can still enjoy legendary Bach tone and playability with the 42F Stradivarius Professional trombone. Instead of a standard rotor, Bach equipped this tenor trombone with their patented Infinity axial flow valve and open wrap design. Together, they alleviate air resistance by lessening the airflow angle and introducing fewer bends in the tubing. The 42F trombone comes with a large 0.547-inch bore and an 8.5-inch yellow brass bell for a focused tone and hall-filling projection. If you’re after a Bb/F tenor trombone that plays like a straight trombone, look no further than the Bach 42F Stradivarius Professional Trombone.

The Infinity valve





The 42F comes equipped with Bach’s Infinity axial flow valve and an open-wrap F attachment. The Infinity Valve diverts air at a much shallower angle than traditional rotors, which gives it a free blowing feel. The conical valve design uses sealed bearings and zero metal-on-metal contact, which greatly increases long-term durability. Beyond the improved valve design, Bach’s open wrap configuration cuts down on wind resistance, giving you the playing feel of a straight trombone. You’ll appreciate the spot-on intonation provided by the separate tuning slide.





1-piece, hand-hammered bell





Bach fitted the 42F 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 42F 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.
