This used Bach 42BGO large-bore tenor trombone, built in the mid-1990s, represents the classic open-wrap 42BO design—one of the most respected professional trombones of the past three decades.
The “G” designation indicates a gold brass bell, which provides a warmer, broader tone and smoother high overtones compared to the standard yellow-brass version. This instrument features an 8.5-inch bell flare, a standard-weight .547 handslide, and an open-wrap F-attachment that allows freer airflow and an even response across all registers.
Previously owned by a professional player, this horn has received a complete service here at The Brass Exchange including a chemical bath, rotor cleaning, and slide alignment. The slide is fast and quiet, the valve is smooth, and the horn is ready to play out of the case.
Gold brass bells are known for producing a rich, centered sound ideal for orchestral, symphonic, and chamber settings. The 42BGO design remains a benchmark instrument for advancing students, university players, and working professionals alike.
This example includes a Bach 42-series case in excellent condition and ships ready for immediate performance use.

✅ FAQs
What does “Used Bach Trombone” mean on The Brass Exchange?
Every used trombone listed here has been inspected, serviced, and play-tested by a professional technician. Instruments are accurately represented and preserved for educational and historical reference after sale.
What makes the 42BGO special?
The “G” stands for gold brass bell — less bright than yellow brass and ideal for players seeking a warm, resonant orchestral tone. The open-wrap rotor design adds free-blowing efficiency and improved low-register response.
Is this a good first professional-level trombone?
Yes. The Bach 42BO and 42BGO have been the industry standard for large-bore tenors for over 30 years, offering consistency, comfort, and world-class sound.
What is an old Bach trombone worth today?
Value depends on era, condition, and originality. Instruments from the Elkhart and early Mt. Vernon periods typically command premiums, but well-kept 1990s and 2000s models like this 42BGO remain highly sought after.
This used Bach 42BGO tenor trombone (mid-1990s) is now part of our Archive of Sold Instruments, preserved here as a historical reference for Bach collectors, educators, and players researching older trombones.
