Yamaha ST7 & PM7 Silent Brass Trumpet Microphone & Personal Studio Headphone Amp

This is a Silent Brass mic and headphone amp set for use on a trumpet! The mic goes in the bell of your horn like a mute, and you can wear the amp on your belt or set it on a surface. There's connection points for 2 of these mute mics on the amp, so if you had a second one, you could practice together on the same amp. The amp gives you control of volume, and gives you some reverb options as well, and provides a basic mix between the two mic inputs as well as the AUX input (through which you might input an accompaniment track to play along with). It can be powered with 6 AA batteries (not included) or the included Yamaha PA-1D power supply. The Silent Brass mute mic itself lowers your trumpet's acoustic volume just like a regular practice mute, but with the amp active, you can dial up the volume on your headphones and blast away without annoying the neighbors. Overall the unit and mic are in good shape, however, the four rubber feet on the amp (that you would normally use to rest it on when using on a tabletop) are missing. Tested and working great. Also includes the 3.5mm cable used to connect the amp and mic.
