Eastman EBB431 BBb Tuba

The model EBB431 is a 4/4 size four-valve BBb tuba. The fourth valve helps with the intonation, tone
and versatility when used in place of the typical one- and three-valve combination. This top-action
instrument is ideal for school and community ensembles that perform more advanced literature. It
includes these important features:

• Key of BBb
• Full-size tuba with 17 1/2” yellow brass upright bell
• Yellow brass construction with rose brass leadpipe and nickel-silver tuning slides 
• Four stainless steel pistons through a .728” bore
• “Euphonium-style” top-action valve assembly 
• Exquisitely finished in a clear lacquer
• Durable, hard-shell ABS case with wheels.
• Includes silver-plated Eastman mouthpiece
