Description The 861 features a traditional German rotary tuba configuration with its long leadpipe and large bore size. It offers a warm deep sound with an abundance of tonal colors, and excellent intonation. Yamaha CC tubas feature hand-lapped pistons and hand-lapped tuning slides for smooth, airtight action. The clear epoxy finish and gold brass leadpipe will provide durable protection against corrosion. 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 valves: 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 positioning: The careful positioning of the tuning slides makes it easier to adjust the slides while playing. Steel wire bell rim reinforcement: The reinforcement of the bell rim improves the strength and response of the YCB-861. Large, handmade bell: Impeccable intonation plus outstanding tone and response are a result of the handmade bell. Fourth valve slide wrap: Uniform response throughout the tuba is assisted by the open wrap fourth valve slide.
