And for the A47BO Artisan Professional tenor trombone, you get a detachable 8.5-inch yellow brass bell with a 47 taper for more power and brilliance. The bell section also features a reverse main tuning slide with a yellow brass crook for a more open feel. A yellow brass hand slide and chrome-plated nickel silver inner slides supply quick, effortless playability. Furthermore, the detachable open-wrap F attachment gives you extra low-end extension and alternate positions to work with. Add your favorite mouthpiece (sold separately), and you’re ready to go.

Cutting-edge modular design





At Sweetwater, we greatly admire that all Bach Artisan trombones offer you the ability to customize and find your ideal sound concept. Almost every part of the instrument can be swapped out, including the bell, hand slide, valve section, and tuning slide. For starters, the A47XN includes three interchangeable leadpipes, each with a different taper and feel. The standard A47XN comes with a 1-piece, 8.5-inch yellow brass bell that sings with a glorious, bright resonance. But if you’ve got a symphony gig coming up, just detach the bell and load up a rose brass bell.

Expressive bell with 47 taper





The A47BO comes with a one-piece, hand-hammered yellow brass bell with a flat wire bead. It measures eight-and-a-half inches across for focused projection to the back of the concert hall. The bell is hammered into Bach’s 47 taper, which has a more dramatic flared end than the standard 42 bells. You’ll enjoy a little more brilliance and power without compromising the legendary sound that Bach trombones are known for.





Removable open-wrap attachment





Professional symphonic players need extra versatility, especially in the low end. And the A47BO obliges, thanks to its F attachment. The attachment features an open-style wrap design and a .547-inch large bore that team up to deliver a warm sound with superb projection. Bach designed the attachment to provide just the right amount of resistance for symphonic players and soloists. What’s more, the horn comes with a silky-smooth rotary valve to engage the attachment. And if you ever want to play a straight horn for a while, take the attachment off and store it in the case. How’s that for convenience?





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.
