The Vibra-Slap makes its sound when the ball end is struck against the palm of the hand. This sound can be varied simply by rotating the sound chamber. This wood version has warm crisp tones while the metal version produces a metallic clatter with longer sustain.
The 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. As with many other LP products, the Vibra-Slap was conceived as a dependable replacement for the original delicate rattling horse jawbone.
