YAMAHA SILENT BRASS SYSTEM for French Horn SB3-9 Yamaha Silent Brass for French Horn Contents: All items are included. Complete set. ● Contents Outer box Inner box Personal Studio ST9 Pickup mute body Connection cable Batteries (old, so they are dead) Stereo earphones (ear pads are deteriorated, so not included) Strap Instruction manual ● Operation check Since the batteries were dead, I bought new ones and checked the operation. I put the new batteries in the trumpet, so they are not included. You will need to purchase batteries to use the system. It works without any problems. It is in working condition. I play the trumpet, and my wife plays the French horn, so I am selling this on her behalf. Like me, she was a member of a community orchestra for two years. She bought this new at that time. I think it was around 20,000 to 21,000 yen. She bought it to use at home, but she hardly used it, so it is in good condition. (Used about twice) The stereo earphones don't seem to be very good, so there may be some noise. You may want to buy new earphones. You can use commercially available earphones; please check the plug pin. Or, you can use it as a silent mute. Due to the lighting, reflections may make it difficult to see scratches in the photos. Free shipping nationwide! Since there is an outer box, I will pack it in cardboard or wrap it in bubble wrap for shipping. I will use recycled materials. I will pack it carefully to prevent damage. This is an old precision instrument, so returns and refunds are not accepted, and no claims are accepted. The French horn in the photo is not included. ● Please understand that the evaluation of whether it is a beautiful item is subjective. Please check the photos.
