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.
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.
