The M500T series has a "Micro-Tune" trigger mechanism. The Dynasty USA design team headed by Wayne Downey with assistance from Jeff Kievit has crafted a clear, responsive and easy blowing horns. Stronger, thicker bracing provides for a solid, quality-feel and sound and the hand-lapped valves provide a tight fit within the casing for smooth air flow, smooth action and to improve the response and intonation of the instrument.

Features include a 9 3/4" (248mm) bell, a .468" (11.89mm) bore, a 17" (432mm) length, a weight of 3 lbs. 11 oz. (1.65kg), a 6V mouthpiece with a trumpet shank (or it can be adapted for a French horn mouthpiece) and a heavy duty travel case. The instrument comes in lacquer finish. The marching F mellophone uses trumpet fingerings, which allows for easy movement of students between trumpet and mellophone.
