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 loved the 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 will be removed from the personal studio before shipping. It will be shipped assembled to protect the bar. Please understand and purchase based on the photos. Anonymous shipping. Immediate purchase is welcome!
