USED Mapex 500 Double Bass Drum Kick Pedal. This Pedal has been loved, but has music left to play-scuffed in some places, shines in others. Refer to images for condition. It has brand new tama iron cobra beaters, cleaned up, oiled and ready to play! Single-chain drives with fully adjustable spring tensions react instantly to your foot. Compact stabilizing radius rods keep the footboard level even at extreme velocities. An independent universal linkage adjustment customizes the beater angle and throw for ergonomic perfection.
