The KM-1 Key Bundle Muffler was developed in collaboration with development with Takashi Kashikura – based on his deep experience as a pro drummer. It is often observed that muting a snare drum often reduces its power and sound. Over the years, drummers have used commercially available mufflers, as well other items around them – and, through experimentation, have created different sounds. The KM-1 is a handy item that provides a unique, exciting sound, and also saves the inconvenience and expense of making a bunch of regular keys.
