This line is discontinued.

The Yamaha Xeno YBL-830 bass trombone features a thin-walled yellow brass bell for enhanced response, a nickel silver slide crook for a good balanced sound, and a new rotor design to improve playability.

• Clear lacquer finish
• Bore: large, 0.563 in. (14.3 mm)
• Bell diameter: 9½ in. (241 mm)
• Yellow brass bell
• Yellow brass outer handslide
• Two inline/independent traditional rotary valves

• Adjustable thumb paddle
• Sprung water key
• Mouthpiece and case included

Along with a larger bore and bell diameter, bass trombones are often equipped with a second rotor to extend their low register. There are two double-rotor systems: ‘independent’ and ‘dependent’. An independent system has both rotors sitting side-by-side (or ‘inline’) on the neck-pipe, where they can function alone or in tandem. Dependent models locate the second rotor on the F attachment rather than the neck-pipe, hence the alternative descriptors ‘stacked’ or ‘offset’. In this configuration, use of the second rotor depends on the first rotor being simultaneously engaged.
