A beater assembly includes a shaft pivotably connected between two supports and a clamping member and a beater are connected to the shaft. A pedal is indirectly connected to the shaft by a chain. A connection member is connected to the shaft and includes a passage in which the clamping member is received. A first bolt extends through the connection member and contacts the clamping member, and a second bolt extends through the connection member and fixes the clamping member to the connection member. The beater and the pedal can be adjusted by loosening the first and second bolts without disengaging the chain from the connection member.
