The Pearl Demonator Chain Drive Double Bass Pedal is a highly adjustable, smooth playing pedal. The Demonator is for playing on a double bass with. It features the Pearl PowerShifter longboard which has 3 positions available to choose from when adjusting the pedal feel. The beater angle is fully adjustable, too, so the possibilities are unlimited! The roller on the pedal is frictionless which allows for the kick pedal to rotate smoothly. The single-chain kick pedal features an aluminum diecast wheel which also contributes to the smoothness of the overall feel of the pedal. The Dual Surface beater gives two different sounds when played on; players can choose from plastic or felt so everyone gets to choose their own style. Kick on, my friends.
