YBB-632S B tuby
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.
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.
The semi-circular shaped hand rest makes the instrument easier to hold and reduces fatigue when holding the instrument for long periods of time.
Developed with top artists
Evaluating the angle of the mouthpiece led to a design that offers a more natural playing position.
A larger brace plate on the bell section delivers a moderate amount of resistance.
