This is a Bach 42B large bore tenor trombone from the 1970s Corporation Era, serial number 42005. The 42B has long been one of the most popular and enduring professional large bore tenors of all time, known for its warm tone, solid projection, and reliability in orchestral and large ensemble settings.
This example features the classic 8.5" yellow brass bell, standard-weight yellow brass .547 handslide, and a traditional rotor F-attachment. It retains all original parts and lacquer and has received a complete professional service and chemical bath in our shop.
The slide is in excellent alignment with straight tubes and no inner slide defects, giving a fast, smooth, and tension-free feel. The valve section is clean, responsive, and seals properly. While this horn shows some cosmetic character from decades of use, its playability and sound quality are exceptional. In the words of our own experience, this is one of the best-playing 42B examples we’ve encountered.
There is one visible mark on the bell flare where a small crease was removed years ago, leaving some lacquer disturbance, but the bell has never suffered major damage. The lacquer has aged gracefully, giving the horn a classic vintage appearance.
It comes in its original Bach case in solid structural condition, though the main leather handle is broken and should be replaced—or the horn can be transported in a modern case if preferred.
