A drum pedal, having a drive assembly supported by a pedestal, may include a drive shaft, a rotatably adjustable drive ring, and a rotatably adjustable beater ring. In another aspect, a drum pedal may have a drive assembly supported by a pedestal comprising a journaled drive shaft, a rotatable bearing mounted off center of the drive shaft, a spring, and a biasing arm pivotally mounted on the pedestal, wherein the bearing and the spring cooperate to bias the arm toward a predetermined rest position. A linkage may operatively connect a foot board and the drive ring and may have means for selectively defining a connection to the foot board from one of plurality of positions. A beater may have a stem affixed to the beater ring. The beater may be actuated to a forward position when the foot board is depressed. The foot board may be biased toward a raised position and the beater may be biased toward a rearward position. In still another aspect, a drum pedal may have a drumward clamp, mountable to a bracket on the base, including a shaft, a rotatable arm, and a torsion spring for biasing the arm toward locking with a drum rim. The arm may be unlocked by rotating a lever connected to the shaft.
