The beater head may form an angle with respect to the shaft and the angle may be adjustable along a range, which may be about 20 degrees to either side of perpendicular. A bass drum beater may also include a shaft, a beater head having a drumward side and a hole to engage the shaft, a beater face attachable to the drumward side, and a means for holding the beater head in a longitudinal position and an angular position with respect to the shaft, wherein the longitudinal position and the angular position are adjustable.
