The Eastman EBF864 Professional Series 5-Valve Tuba combines traditional design and craftsmanship with the consistency of modern manufacturing. This full size tuba delivers the sound of a Germanic rotary F tuba with a fluid low register and great intonation throughout the tonal range. Finished in silver-plating, the tuba features five right-hand rotary valves through a graduated .667" to .820" bore and a yellow brass upright bell. Versatile and reliable, the Pro Series Tuba is equally suited for solo performances as well as part of an orchestra or small ensemble.
