SB3X Yamaha YAMAHA This is a Silent Brass for French horn. I purchased it and used it about twice, but I'm busy and don't have a chance to use it, so I'm selling it. I remember purchasing it about 3 years ago. I will not include the warranty card as it contains personal information, but all other manuals are included. There are almost no scratches, and although it's been stored by a non-professional, it can be said to be in good condition. Operation confirmed. Recommended for students in the brass band club and those who play the horn as a hobby. It has a mute function that allows you to play at night without any problems, so your practice will be more productive. The current model is SB3J, which costs 35,200 yen. The SB3X being sold is the previous model, but the main differences are whether it can connect via USB and whether it has reverb. This one is sufficient for practice. Although not recommended by the manufacturer, it worked fine with a marching horn (B♭).
