This is a chain-drive single pedal and includes a woven-nylon strap that can be installed using a drum key. There are adjustments for beater angle, footboard angle, and spring tension on this pedal. A teardrop-shaped hole in the beater hub securely holds the beater shaft and keeps it from spinning. Included is a double-sided beater that is felt on one side, and hard plastic on the other. The side-adjustable hoop clamp holds firmly to your kick drum hoop, and tightens with a wing bolt.
