Berkeley Bb/F Bass Trombone is my favorite designed special for the valve, make so smooth and fast,also have large bore Bass trombone was developed for players who wanted a lighter, centered, soloist trombone with fast response.
With the full bore .562" CR rotary valve and a light, one piece hand hammered Silver bell carefully matched with a Silver tuning slide and hand slide, this trombone have malleable tone, providing the working player and soloist with an instrument which allows your distinctive style to project effortlessly.
The hand slide is slightly narrower allowing for a more comfortable grip for those players with medium size hands. We've also improved the response of the hand slide with nickel outer sleeves turned to .010". This allows effortless playing, but their weight and hardness improve projection and tone at higher volumes. .547" Slide - .562" F Section 8 1/2" Diameter Interchangeable 562" Kanstul CR Valve Finish:Silver
