A drum pedal assembly for connecting a first pedal to a support holding a
beater arm may include a telescoping transmission shaft having yokes
attached to shaft ends, yokes having bosses, universal joints rotatably
attached to bosses and using trunnions, second yokes having bosses
attached to universal joints using additional trunnions. The second yokes
may rotatably attach a drive assembly rotatably attached to first pedal
