The Earthworks KickPad is a pad/EQ processor for all cardioid mics used to attenuate kick drums. Just plug the KickPad into the mic line feeding your favorite cardioid bass drum mic and you will experience an incredible "instant kick drum sound" that is exactly repeatable, every time. This is a real time saver that will work with any cardioid microphone that is used for kick drum. The KickPad is a passive device (requiring no phantom power) that can be used with either condenser or dynamic cardioid microphones. It will provide fantastic results for both recording and live sound applications.
