Pearl Crystal Beat 4 Piece Shell Pack Drum Kit - Tangerine Glass 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 rigors of touring. Crystal Beat's toms include the Opti-Mount suspension system to remove undue shell pressure and increase sustain. 1.6mm triple-flanged hoops offer just the right amount of attack without sacrificing tonal body.
