The LP Vibra-Slap was the first of numerous patents granted to Latin Percussion. It has appeared in more recordings, soundtracks, and advertisements than any sound effect ever made. The Vibra-Slap was conceived as a durable replacement for the original delicate rattling horse jawbone. Sound is created when the ball end is struck against the palm of the hand. Sound can be varied simply by rotating the sound chamber. This wood version has warm crisp tones.
