This Bach 50B30 bass trombone, serial #221353, was built within the past few years and remains in like-new, showroom-perfect condition. It has been barely played and looks as if it just left the factory—no blemishes, wear, or mechanical issues of any kind.
The 50B30 is one of Bach’s most versatile professional bass trombones, featuring the classic 9.5" yellow brass bell for a rich, powerful, and balanced tone. Its open-wrap dual rotor system is configured in Gb/D tuning, allowing excellent airflow, effortless response, and improved flexibility in all valve combinations.
The standard-weight yellow-brass handslide offers precise control and clear articulation while maintaining the depth and power expected from a Bach large-bore bass. The slide action is smooth, quiet, and tension-free—exactly as it should be on an instrument of this caliber.
A new Bach 50B30 currently retails for well over $6,000–$6,400 USD, and long factory lead times are not uncommon. Having one in this condition, available immediately, presents a rare opportunity for serious players seeking a premium instrument without delay.
Includes the original Bach case, and we offer a selection of Doug Elliott bass trombone mouthpieces on our accessories page to further customize your playing setup.
