Abstract: This invention discloses a novel and improved mechanism for operating a bass drum which is totally adjustable. A telescoping rod and tube assembly is provided whereby the position and the height of the foot pedal may be adjusted to suit the operator's individual needs. The position of the mechanism may be arcuately adjusted about the drum head as well as the distance through which the beater ball moves to strike the drum head and the force required to be exerted on the depressible foot pedal to cause the beater ball to move. These various adjustments may be made singly or in concert.
