A great kick drum microphone needs to be designed and optimized for that specific purpose. This means the microphone is great for kick drum and nothing else. To create a more versatile product we designed the kick drum optimization in an external XLR package - the KickPad. Just plug a KickPad into the mic line going to the SR25 kick drum mic for magnificent results. With the KickPad removed, you can use the same SR25 microphone for most anything. All three high quality Earthworks microphones in the DrumKit System can be used for other instruments and vocals. The KickPad will also improve the sound of other popular microphones used for kick drum.
