Pearl Reference Series Bass Drum (20x18 inch Purple Craze)

Pearl Reference Series The missionWhat if each drum in your drum set was engineered as an instrument unto itself. Each tom designed to respond perfectly within the confines of its respective frequency without compromise over any other area of your kit. This is the mission behind Reference Series.

The 10" and 8" toms receive 4 plies of Maple with 2 inner plies of Birch for cut and attack. And for maximum response, all 13" and smaller toms have a rounded 45 bearing edge.And for 13" toms and lar...
