Abstract: In order to enable the instruments of a percussive instrument assembly to be located where desired and to prevent the instruments from moving away from the player, anchoring devices are disposed in clamping relationship with a removable rug on which the instrument assembly is disposed. The devices have opposite edge surfaces one of which in concave and preferably has a notch or undercut. The devices are located were desired by the player through the rugs and receive the legs or other appendages of the percussive instruments thereby anchoring them permanently in place and preventing movement when the instruments are struck or are foot operated by foot pedals the operation of which results in forces pushing kick drums and cymbal assemblies (hi-hat) away from the player. The anchoring devices may be called "Drum Ruggers".
