The TB-400 is a solid straight tenor trombone for beginners and advancing players. It features a .500" medium-large bore and an 8" yellow brass bell — a combination that balances comfortable resistance with enough openness for a warm, full sound. The nickel-plated inner slide provides smooth, responsive action that makes position changes feel effortless.

Each TB-400 is set up and play-tested by NAPBIRT-certified technicians before shipping. It arrives ready to play with dependable intonation and consistent response across the range. Includes a contoured carrying case — a reliable trombone that will serve a student well through middle school, high school, and beyond.
