XO1240L Professional Series Bass Trombone 1240L Yellow Brass Bell
Independent shopping perspective
The Korena take
Built for advancing professional players, the XO 1240L is a Bb/F/Gb/D bass trombone with an independent valve system and standard rotors. Its 9.5-inch handcrafted yellow brass bell is paired with a .571-inch bore and open wrap. Three interchangeable leadpipes—two yellow brass and one sterling silver—let the player alter the instrument’s setup for their preferred performance response. Yellow brass outer handslide tubes, a nickel-silver crook, lacquer finish, mouthpiece, and case round out the configuration.
Strong match

- Professional bass trombone work requiring Bb/F/Gb/D tuning and independent valve operation.
- Players who want to customize setup through three interchangeable leadpipes.
- Performers seeking an open-wrap bass trombone with a 9.5-inch handcrafted yellow brass bell.
Consider the trade-offs
When to look elsewhere
- Players who need a trombone other than a Bb/F/Gb/D bass trombone.
- Those who do not want an independent valve system with standard rotors.
