This is a YAMAHA euphonium. I've had it for quite a few years since I bought it, but it's in good condition, so I'd like to pass it on to someone who will use it. Brand: YAMAHA Product Name: Euphonium Model: YEP621S Included: Body, Mouthpiece (unused), Hard case I used a different mouthpiece, so the included one is unused. I bought it new in 2009 and used it about a few times a month for about half a year to a year. I handled it with care, so there are no major scratches or dents. Upon close inspection, there are a few minor scratches (not visible in the photos due to reflection), but I cleaned it occasionally, and the storage condition is good, with almost no discoloration, so I think it's in pretty good condition. (However, the water key is as is, and some maintenance of the valves using oil may be necessary) → Simple maintenance has been completed. (Grease and valve oil used for maintenance will be included as a bonus) I will pack it in the hard case with bubble wrap and ship it. Thank you for looking. Added 2/21: Today, I have completed the inspection and maintenance of all tuning slides and pistons. (Grease and valve oil used for maintenance will be included as a bonus) The price has been changed due to a purchase request.
