Yamaha YBB-632 Neo Bb Tuba

The Yamaha YBB-632 Neo Bb Tuba was designed in co-operation with Simon Gresswell to meet the needs of all brass bands. The design incorporates a large 500mm diameter bell that keeps the sound focused and always clear. It delivers a rich tone and abundant volume that provides the ensemble with a solid and stable foundation. Yamaha’s professional model background brass are world-renown for their blend of traditional warm, rich sound, combined with highly accurate intonation and easy playability. Developed in close co-operation with top artists, they represent the state-of-the-art in brass instrument design and manufacture, and are ideal for either solo performance or providing a secure foundation for any ensemble.

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

Artist Message:

Simon Gresswell – BB♭Bass

[Principal Tuba, Brighouse and Rastrick Band]

It was an honour to be asked by Yamaha to help develop the new Neo BBb Bass.

I was looking to create an unrivalled sound base, capable of holding together in all ranges and dynamics. The valve action is quiet and slick, allowing clear movement and definition. The lower register is of special quality. It is easy to produce allowing maximum control and colour. This instrument exceeds all my expectations of a modern day BBb Bass.
