Construction
Pearl has made shells for more than 30 companies. In the 1960s, they ceased making shells for other companies, and began manufacturing drums under their own name and used the Pearl logo for the first time.
Their construction technique is known as SST or "Superior Shell Technology." All Pearl drums feature this construction. Each ply is placed into a cylinder, and pressure is applied from both sides. While in the press, the shell is heated to bring the glue to a boil, thus forcing it through the wood grain and fusing the shells very tightly. The individual plies are scarf jointed, and all the seams are offset, resulting in a "seamless" drum (Pearl demonstrates the strength by parking a Humvee with its tire on a tom shell). This creates a drum shell of incredible strength.
