Eastman EBF866S F Tuba Overview
The Eastman EBF866S Professional Series is a 6-valve, 4/4 F tuba built for advanced and professional performance, combining a full-size wrap with four right-hand rotary valves plus two left-hand rotary valves for expanded low-register control and alternate fingering options. Designed around a .667 inch to .820 inch bore and a 16.5 inch upright yellow brass bell, it is voiced for a clear, centered “Germanic” sound that suits orchestral, chamber, and solo repertoire, and it ships with a deluxe wheeled case for practical transport protection.

Who the EBF866S F Tuba Is For
The Eastman EBF866S is a professional 6-valve 4/4 F tuba designed for experienced tuba players who need a secure, consistent low register and flexible fingering options in an F tuba format.
This model is well-suited to orchestral literature, chamber brass, and solo work where clarity and pitch stability matter, and its two left-hand valves (including the sixth valve) are especially valuable for alternate fingerings that help even out response and tone in the low register. Within Eastman’s lineup, the EBF866S is positioned as a top-tier F tuba for players looking for a distinctly Germanic-style core and a rotary-valve feel.
