Yamaha YBB-105MSWC 3/4 BBb Convertible Tuba, silver

Catalog: YBB-105MSWC

Price: $6116.99


Marching 3/4 size model converts easily for concert band use.

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.

Precision brace design and placement

The design and placement of the braces ensure maximum durability as well as optimum tone.

Bore size

The .661" bore of the YBB-105M achieves the ideal balance between easy response and solid, authoritative sound.

Bell flare

The specially designed bell flare delivers outstanding projection with warm, rich tone.

Leadpipe taper

Faultless intonation and well-centered notes are the result of the extended taper on the leadpipe.


The YBB-105M has been designed so it is easy to handle while marching.

Heavy bracing throughout

Because this tuba is used in marching band, it has heavy bracing throughout the instrument to make it more durable at the vulnerable points.
