A while ago, I wanted to play the trumpet, which I'd always admired, so I bought an instrument and also purchased this unit for practicing at night. However, due to work and the fact that I'm the type to be satisfied with just buying things, I'm selling the trumpet, which is almost unused, and I'm also listing this unit since I won't be using it in the future. The outer box shows its age, but the contents are almost unused. The mute part was only attached to the trumpet a few times, and the rest is unused. The CD is also unopened. I confirmed that the main unit powers on when plugged in with an adapter. The included accessories are all shown in the photos. This is a YAMAHA Silent BRASS SB7 silencer for trumpets. A limited edition CD is included. The box shows some scratches and dirt from age, but the contents are almost unused. This is the perfect item for trumpet practice.

No pets, no smokers. Thank you.
