This is a YEP621 euphonium. I purchased this instrument in excellent condition this year, having only been test-played, and have been taking care of it. I am selling it to organize my instruments as I haven't had much opportunity to play it. The current list price is 478,500 yen. While there are some minor polishing scratches and slight aging from maintenance, I believe it is in excellent condition. It feels like a Yamaha instrument, producing a good sound from low to high registers. A Yamaha 51 mouthpiece is included. All pistons and slides move smoothly. The case is relatively clean, with no cracks in the handle. Two keys are included. Although it has been used only a few times, please refrain from purchasing if you are looking for a perfect item. It will be shipped with careful bubble wrap packaging.
