A beater weight assembly for a drum pedal comprises an adjustable main weight member as well as add-on weights selectively affixed to the main weight member. The main weight member is carried by the beater shaft. By adjusting the position and amount of the weight, the distribution of weight acting on the rotary element is altered to affect the balance point of the stroke of the beater element as well as rotational forces influencing the character of the beater stroke. The add-on weights may be affixed to the main weight member without removing the main weight member from the beater shaft.
