The KM-1 Key Bundle Muffler was developed in collaboration 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 or other items lying around and, through experimentation, have created different sounds. The KM-1 is a handy item that provides a unique, exciting sound, and can be used in several ways. The strong magnet allows the bundle to be attached anywhere. Nine key blanks are bundled on three key rings, allowing the unit to be very adjustable, or even split to be used in mutliple places at once.
