This is for the Yamaha Silent Brass for Euphonium (SB2X). I purchased it during the COVID pandemic so I could practice at home, and I've stored it without using it much, so there are almost no scratches. Operation has been confirmed. The product box is not included, so it will be disassembled and wrapped in bubble wrap for shipping in a different box. Earphones are not included, so please use your own. The instruction manual is also missing. There are some scratches from having been used a few times, so please purchase only if you understand this.
