Who the YBL-835 Xeno Bass Trombone Is For
The YBL-835 is intended for professional players, advanced students, and serious ensemble musicians who want a heavyweight bass trombone with independent valve control and a substantial, centered tonal foundation.

Common Questions About the Yamaha YBL-835
What does the in-line valve configuration offer?
The two in-line rotary valves provide Bb/F/Gb/D tuning and allow the player to use each valve independently. This supports alternate positions and flexible access throughout the bass trombone's low register.
How does the YBL-835 differ from the Yamaha YBL-822G?
The YBL-835 uses in-line valves and a yellow brass bell. The YBL-822G uses offset valves, a gold brass bell, and a detachable second valve, reflecting a different approach to balance, valve layout, and tonal concept.
How do the large bore and 9-1/2-inch bell affect the design?
The 0.563-inch bore supports the airflow expected of a professional bass trombone, while the 9-1/2-inch bell contributes to a broad low-register sound and strong ensemble presence.
