ABSTRACT:
An improved drum pedal for use with an acoustic or electronic bass drum has sprocket wheel 78 mounted for rotation on the toe end of a foot pedal 16. A rotational torque applied to a sprocket 72 attached to a crossarm 22 and in turn to a mallet head 28 causes mallet head 28 to swing through an arc 3 toward the drum head. Sprocket 72 and sprocket wheel 78 are connected by chain 76 in a compound pulley system wherein chain 76 is attached at one end to sprocket 72 and is wrapped around and under sprocket wheel 78 to be fixed at its other end at mounting bar 80, so that a downward motion of foot pedal 16 and sprocket wheel 78 through arc 2 moves sprocket 72 and mallet head 28 through arc 3, which motion is twice the magnitude in distance and velocity as that of sprocket wheel 78.
