In 1973 Pearl set a benchmark in the drumming world with the introduction of Crystal Beat. A stunning combination of visual appeal and powerful sonic attack Crystal Beat s revolutionary seamless construction was molded -not rolled- creating a strong acrylic drum system that could stand up to the riggors of touring. The shells of the Crystal Beat series produce fat attack with big projection and clipped resonance. Tom and share shells are 6mm thick while the kick drum measures 7mm. The drums are fitted with 1.6mm triple-flanged hoops for just the right amount of attack without sacrificing tonal body. Crystal Beat s toms include the Opti-Mount suspension system to remove undue shell pressure and increase sustain. Additional hardware features include Air Suspension floor tom feet molded rubber gaskets and telescoping spurs with rubber or spike tip. Snare cymbals and hardware sold separately. Includes limited two-year manufacturer warranty.
