YEP621S I purchased this new and have only used it for three months. I am selling it because I no longer need it. I used it with care, so there are no noticeable scratches or stains. It comes with a mouthpiece, hard case, and manual. Please refrain from purchasing if you are overly concerned about minor details, as it has been used for three months. [Brand] YAMAHA [Category] Euphonium [Condition] No noticeable scratches or stains B♭ tuning. Valve system is 4-piston. The bell is yellow brass, 280mm in diameter, with a bore size of 14.5mm (1st-3rd) / 16.8mm (4th), silver-plated finish. "Exceptionally powerful and enveloping low range. It responds to the musician's musical ideas with a rich sound. Expressiveness that can be used widely, from British-style brass bands to concert band sounds. Thick and full low range and a clear, well-defined sound. It achieves a comfortable resistance and flexible control. Accurate intonation, including the 6th overtone F. Furthermore, excellent operability also supports the player. Yamaha euphonium that expresses the player's thoughts without reservation. YEP-621S, which adopts a side-action 4th piston." Thank you.
