The Shure DMK57-52 Drum Microphone kit is a special package for drummers comprised of one Beta 52 bass drum mic and three SM57 dynamic microphones. There are also three A56D drum mounting clamps for the three 57s and it all comes in a lightweight and durable carrying case. The cardioid SM57 is perfect for snare drum and toms and the universal A56D mounting kit makes positioning them just where you want easy. I like the Beta 52 for kick drums because its frequency response enhances most of the wanted frequencies for a better recorded or live sound.
