Comfort and durability accent the smooth action of this professional tuba from Yamaha band instruments. The 641 professional BBb tuba features a unique rotary valve configuration for a traditional Teutonic sound with the kind of precise intonation and easy playability only made possible by modern engineering expertise. The Yamaha YBB-641 is characterized by a warm dark tone and an abundance of tonal colors. Yamaha BB Tubas feature hand-lapped pistons and tuning slides for smooth, airtight action. The clear epoxy finish and gold-brass leadpipe provide durable protection against corrosion.

Yamaha YBB-641 Model Options

Yamaha offers a number of variable options for select instruments.

• YBB-641S - Same specifications as the YBB-641, except silver plated

Features

• 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.
