The Yamaha YBB-621 is an attractive, durable, and professional tuba with uniquely smooth playing action. All Yamaha Bb Tubas feature hand-lapped pistons and tuning slides for smooth, airtight action that sounds in all registers of the instrument. The clear epoxy finish and gold-brass leadpipe provide durable protection against corrosion. Available also with a silver-plated finish for a unique tuba look and tone.

YBB-621 Model Options

Yamaha offers a number of variable options for select instruments.

• YBB-621S - Same as YBB-621; except silver-plated

Features

• Monel pistons: Monel pistons are resistant to corrosion and are an ideal choice for professional baritone pistons which must retain precise fit and smooth action over many years.
• Hand-lapped pistons: 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.
• Available feature: The YBB-621 tuba is available with a silver-plated finish
