Engineered for the discerning tubist, this professional F tuba combines Germanic rotary valve construction with precision bore engineering. The graduated 0.667–0.820-inch bore expands into a 16.5-inch yellow brass bell, delivering a resonant, full-bodied tone with exceptional intonation across all registers. Five right-hand rotary valves provide responsive control, while the hand-adjustable 1st valve slide enables real-time tuning refinement during performance. Includes a wheeled deluxe case for secure transport and storage.
