A spring return for a bass drum pedal includes a spring with ears at opposing ends, one ear connected to the pedal frame and the other ear connected to a pivot arm attached to the pedal driveshaft. The pivot arm includes a hub mounted on the driveshaft and a shaft extending radially therefrom. A collar is journaled on the shaft and includes a setscrew to permit selectively locking of the collar at desired locations along the shaft. A pin mounted on the collar has an aperture for receiving one ear of the spring, thereby permitting selective adjustment of the distance between the spring ear and the driveshaft, to thereby adjust the ratio of driveshaft rotation to spring pressure.
