Bach 42B with "K" Valve — Open Wrap, Corporation Era Slide
The Bach 42BO-K tenor trombone combines some of the most desirable features for serious players seeking flexibility and a rich, resonant sound. This particular instrument features an open wrap yellow brass 42 bell section paired with the "K" valve, a modern rotor design known for its open feel and smooth transitions.
The bell and valve section have received a full overhaul, including fresh lacquer, and are in perfect condition — visually stunning and fully ready for professional use. The valve plays open and resonant, offering a free-blowing feel that makes it easy to shape phrases in any register.
The handslide is a standard weight slide from the 1970s Bach "Corporation Era," a period prized for quality craftsmanship and excellent materials. This slide moves easily with no service needs required to improve playability. Together, the combination of new bell/valve and vintage slide makes for a unique, responsive, and versatile trombone that will suit a wide range of playing contexts.
Players will enjoy the characteristic Bach overtones and broad, warm sound across all registers. This 42BO-K would make a fantastic all-around tenor trombone for any serious musician, whether performing orchestral repertoire, chamber music, or solo works. The instrument is equally suited to advancing students stepping into professional-level gear or seasoned players looking to expand their tonal palette.
This trombone comes with a classic Bach "coffin" style case in fair condition, fully functional but showing cosmetic wear from use. A mouthpiece is not included, allowing the next owner to pair it with their preferred setup.
