About the Yamaha YSL-882IIGO Xeno Series Trigger Trombone, Open Wrap, Gold Brass Bell:
 
Upgraded Lever Action
The lever action has been completely upgraded with a shorter stroke that affords vastly improved operability. Other refinements include a double torsion spring that contributes to consistent, smooth lever operation, and double ball bearings that significantly reduce the need for maintenance—and make it incredibly easy when it does become necessary.
 
Standard Xeno Bell
This trombone is equipped with a slightly oversized 220 mm (8-2/3 inch) bell, which is the premium standard found across the Xeno trombone lineup.
 
 
Open Wrap F Attachment
The F attachment features a gentle open wrap design. This configuration minimizes changes in blowing resistance when the F attachment is engaged, resulting in a freer, more uniform overall playing feel and consistent resistance across all registers.
 
Yellow-Brass Narrow Slide
A yellow-brass narrow slide contributes to a smooth, delicate tone that remains clear and well-defined. This design provides players with comfortable playing resistance alongside ample power and brilliance when needed.
 
Compact Balancer
The compact balancer design perfectly manages the instrument's weight distribution while helping to deliver a well-focused, core sound.
