The Yamaha YEP642II Neo Professional Trigger Euphonium produces a powerful projection, ideal for the professional musician. The main tube has increased resistance which can be used by experienced players to achieve a more expressive response. The yellow brass body has a punchy low frequency response with high end clarity. The adjustable trigger rod provides players with even control of their playing and creates a very dark and rich sound due to the additional weight of the trigger. This model has a silver finish for a classic look and comes equipped with a hard case and SL-51L mouthpiece.
