Abstract: A magnetic resistance system for use with drum sets that allows for various levels of magnetic repulsion between a drum beater and a batter head. A drum beater having a beater magnet is used in conjunction with an impact pad having an impact magnet. The drum beater is attached to a drum pedal, while the impact pad is integrated with the batter head of the drum, either directly or through a suspension bracket.
