Bb euphonium with yellow brass body with silver-plated finish and 300mm bell diameter from Neo series that features a main-tuning slide trigger system, offering enhanced, precise pitch control as well as solid tone. The lever plate can be pressed during a performance to shift the main tuning slide downward, lowering pitch by a precisely controlled amount. The position, angle, and stroke of the lever plate can be further adjusted to optimize trigger system operation and comfort individual needs. The main tube tuning slides have a rod base to which the trigger rod attaches. Additionally, the diameter of the main tube tuning slide inner tube is smaller than normal to ensure smooth trigger operation. A special metal cover prevents the main tube tuning slide from coming into to direct contact with and possibly transferring oil to the player’s clothing. The euphonium has three top plus one side valves and comes supplied with a case and a 2mm hex wrench for lever plate vertical position and angle adjustment. Bore size: 15-16.8mm. Height: 664 mm.
