Double Bass Drum Pedal (PDDP502) Designed by industry leader Drum Workshop, PDP hardware is built to perform for working drummers. The 500 Series Double Pedal delivers exceptional quality for less than you might think. The DP502 pedalboard design has a sleek, racing-inspired look and features a Dual Chain Drive Offset Cam on each side. The linkage between the pedals has a responsive touch and the solid feel under your feet comes from the steel base plates, built-in spurs and the key-side-adjust hoop clamp. Several points of adjustment (beater angle/pedal height, standard spring tension adjustment, and beater height adjust), 2-way beaters and a built-in drum key clip allow you to dial the feel in quickly to perfectly fit your style. 500 Series Dual Chain Drive with Offset Cams 400/500 Series linkage and universal joint PDAX101 2-Way Beaters Dual Steel base Plates Built-in spurs, key side adjust hoop clamp, drum key clip & key.
