Gong Bass Drums The ultimate low sound - MRP Gong Bass Drums are positively thunderous! Our design allows the drum head to resonate much more freely compared to other designs where the head and counter hoop are oversized then forced over the shell, therefore choking any available resonance. When you need a low end rumble beyond what a floor tom can deliver, MRP Gong Bass Drums give you the deepest low end sound anywhere!
