Add Vic Firth Heavy Hitter Laminates to the Vic Firth Stock Pad or Slim Pad for great simulation of the response and feel of a marching drum. Vic Firth Heavy Hitter Laminates are heavy duty Mylar discs equipped with a special double-sided adhesive. Simply peel off the backing and apply to the Vic Firth Heavy Hitter pad of your choice. Because of the easy peel-and-stick feature the Laminate can be added replaced or upgraded at any time.
