Yamaha Silent Brass for Euphonium. Everything in the photos is included. Please purchase only if you know how to use it. I purchased this here. I was very pleased with its high muting performance, but the weight of the Silent Brass was too much for me, so I am selling it. Thank you to the previous seller. This is a used item, and its operation has been confirmed. The batteries for the personal studio will be removed before shipping. It will be shipped assembled to protect the bar. Please be satisfied with the photos before purchasing. Anonymous shipping. Immediate purchase is welcome!
