Love this for playing drums.
Our band plays with IEMs both live and for practice. I made a custom plate and mounted this little guy to my throne and picked up a second hand amp to run it assuming it would be a novelty. I'm at the point now where I really dislike playing without it. It adds so much to the experience. I use an output from our digital mixer to run my floor toms, kick, and our bass players channel to my amp. This really helps me lock in with the bass as I can feel the groove. Net net, love this thing.
