Eastman F tuba EBF865s silver - new model

Professional Eastman EBF865S silver-plated F tuba with five rotary valves and tuning trigger

The Eastman EBF865S Silver-Plated F Tuba is a new professional 4/4 model developed for tuba players seeking precise response, tonal stability and controlled articulation. Its five front-action rotary valves provide different fingering possibilities for demanding musical repertoire.

One of its most distinctive features is the five front-action rotary valve system. This arrangement provides a fully rotary mechanism, unlike tubas combining pistons and rotary valves. It is particularly interesting for players familiar with this type of valve configuration.

The EBF865S features a second valve slide trigger, allowing the player to adjust the tubing length during performance. This mechanism provides an additional means of making specific tuning corrections without interrupting the musical passage.

Its 420 mm Yellow Brass bell (16.5 inches) forms part of a construction designed to deliver a defined sound with strong presence. The 4/4 size offers proportions suitable for orchestral repertoire, chamber music and solo works.

The variable 18–21 mm bore (0.708"–0.826") completes the instrument's specifications. Its silver-plated finish provides a distinctive appearance, and the instrument comes with a mouthpiece, Ultra-Pure maintenance kit and ABS hard case.

Benefits of the Eastman EBF865S F Tuba for Professional Players

The five rotary valve configuration provides different fingering combinations and allows players to approach technical passages using a fully rotary mechanism. This feature is particularly relevant for musicians who prefer rotary valves over piston-based configurations.

The second valve slide trigger allows tuning corrections to be made during performance. It is especially useful in passages where individual notes require specific adjustments, including orchestral and chamber music repertoire.

The combination of a 420 mm Yellow Brass bell and a variable 18–21 mm bore defines important aspects of its acoustic construction. These dimensions distinguish the EBF865S from other Eastman F tubas featuring different bell sizes and valve systems.

The silver-plated finish visually distinguishes the EBF865S, while the ABS hard case helps protect the instrument during transportation. The Ultra-Pure maintenance kit provides products for regular instrument care.
