■ Item YAMAHA Silent Brass SB3 for French Horn. It's old, but everything is included, including the box. I no longer needed it because I installed a soundproof room a few years ago. You can select from three modes: "Rehearsal Room," "Concert Hall," and "Church," and the sound is very good. Hardly any sound leaks out to the surroundings, making practice very enjoyable. The only downside is that you might get the illusion that you've become better! (lol) Purchased in 1996. - Brand: YAMAHA - Product Name: Silent Brass SB3 - Intended Use: For French Horn ■ Condition Basic operation has been confirmed. I have always stored it in the box, so I don't think there are any major stains. The box has deteriorated and has been partially repaired with tape. I feel that the cushion rubber attached to the mute insertion part is deteriorating. Also, the instruction manual has deteriorated considerably, with insect damage, and has been partially repaired with tape. Please refer to the photos. This is a used item, so please understand this before purchasing.
