Yamaha YBB-105WC 3/4 BBb Tuba — Lighter, Louder, and School-Ready
The Yamaha YBB-105WC is the ultimate student tuba: compact enough for younger players to hold comfortably, yet powerful enough to fill a band room with a warm, full sound. Its 3/4 size design and lightweight build make it easier to play, reducing fatigue and improving posture—perfect for middle school and high school musicians who are still growing into their instrument.
Unlike tubas that ship straight from a warehouse, every YBB-105WC from AAA Band Rentals is professionally set up by our in-house brass technicians. Valves are aligned, slides are greased, and the instrument is play-tested so your student is ready from day one. Add in our local service centers in Norwalk and Cos Cob, same-day school delivery, and loaner coverage during repairs, and you’ve got a purchase that’s worry-free for parents and band directors alike.
Why players and directors love it:
Comfortable 3/4 size with easy-to-reach top-action valves
Big, focused tone that blends beautifully in concert band
Durable nickel-plated pistons and epoxy lacquer finish built for school use
Comes with a wheeled hard case and a Yamaha 67 mouthpiece for mobility and reliability
Supported locally with priority repairs, cleanings, and director-preferred service
