The Adams F5 is combination of vintage sound concepts combined with advancements in modern technology. This instrument features Adams' short action valves and a specially designed bell that complements the chassis. The Adams short-action valves are a straight, direct-air column ported valve-set with a compact feel and fast action. The special bell's profound resonance makes for a pure, rich, warm and very fluid flugelhorn. This horn is equipped with a full copper bell, which further enhances the instrument's lush and rich timbre.
