Yamaha YBB641 BBb 4/4 size Professional Rotary Tuba (With Case)
Comfort and durability complement the smooth action of this professional tuba.
Hand-lapped rotary valves
Hand-lapping is a time-consuming finishing process which results in superior valve fit for noiseless, responsive action and easy tone changes.
Hand-lapped slides
Hand-lapping achieves the perfect balance between airtightness and smooth action.
Nickel-silver spatula keys
Carefully positioned nickel-silver spatula keys are strong and are capable of comfortable fast fingering.
Ball joints for rotary valve levers
The Yamaha-developed ball joints for the rotary valve levers are durable, yet achieve silent operation and light action.
Leadpipe
The long leadpipe contributes to a beautiful, dark, smooth tone which blends well with other instruments.
Tuning slide position
The careful positioning of the tuning slide makes it easier to adjust the slides while playing.
