YBB-632S BBb Tubas
Large Diameter Bell
At 500mm, this is the largest bell among Yamaha BBb basses. Its size greatly improves dynamic range while delivering a stable sound that envelops the entire ensemble.
Bore Size
The bore size offers freer blowing with a moderate amount of resistance.
Fourth Valve Position
An ergonomically repositioned fourth valve offers improved playability and makes fast passages easier to play.
Repositioned First to Third Valves
After a thorough evaluation of valve positioning, a new design promotes a more comfortable playing posture.
Handrest Design
The semi-circular shaped hand rest makes the instrument easier to hold and reduces fatigue when holding the instrument for long periods of time.
New leadpipe design
A new leadpipe taper offers improved resistance. Evaluating the angle of the mouthpiece led to a design that offers a more natural playing position.
Large Brace
A larger brace plate on the bell section delivers a moderate amount of resistance.
Hardcase: BBC-632
