Manufacturer: YAMAHA Model Number: YEP-201 [Product Condition] Sound output confirmed. There is some stiffness in the tubing. There are dents, scratches, and rust, but it is playable. It is a 3-valve model. I was in a school brass band and have experience with euphonium... In terms of usability, it's a bit harder to blow compared to school-owned instruments, and it requires a bit of skill to produce a beautiful sound. However, it is in a usable condition for practice at home. We recommend using it for practice at home, not for school practice or performances like competitions! [Notes] The main body has been lightly cleaned before listing, but maintenance such as valve oil is essential when using it, so please be sure to apply oil! *Mouthpiece is not included!!! (It is a standard size mouthpiece for euphonium.) [Accessories] Main body only The condition is as shown in the images. As this is a used instrument, please refrain from purchasing if you are concerned about minor details. Also, please understand that we cannot guarantee its operation. We are open to reasonable price negotiations, so please feel free to comment!
