These things are great for drummers, and do exactly what they say. I’m using them right now. For smaller clubs and rehearsals, they’re great for bringing down the level of the cymbals without sacrificing tone. They still sing, but the volume is reduced. It really works. I just use a small one on the bell. The snare has them on top and bottom. It’s fat and crisp, without ringing when the toms are hit, kinda like the old wallet trick, but better. Toms don’t ring throughout the whole song, but sound great with a small one on the bottom head and a medium one on top. The boing is gone, but the tone is still there. Way better than getting a plastic shield, the kit sounds tight, but not super loud. Check them out.
