■ Item YAMAHA Silent Brass SB3 for French Horn. It's old, but everything is included, including the box. You can select from 3 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 downside is that you might get the illusion that you've become better. (lol) - Brand: YAMAHA - Product Name: Silent Brass SB3 - Intended Use: For French Horn ■ Condition Basic operation has been confirmed. It has always been stored in its box, so I don't think there are any major stains. Part of the rubber on the controller has peeled off (see photo 10). The cushion rubber attached to the mute insertion part seems to be deteriorating. Please refer to the photos. This is a used item, so please understand and purchase accordingly.
