The DFP-8500C is a double chain drive double pedal. The DFP-8500C has adjustments for beater angle, footboard angle, and spring tension. The pedal frames have stabilizer bars cast into them below the rocker shafts to eliminate flex. This keeps the bearings in alignment and gives the pedal a smooth feel. The footboards are longer and wider for a solid feel, and make it great for anyone that uses a heel/toe technique. The hole in the beater hubs are tear drop shaped so it securely holds the beater shaft. The DFP-8500C ships with our hard felt beaters that have been a favorite of many of Yamaha's artists for years. The side-adjustable hoop clamp holds firmly to different thickness hoops, and tightens with a wing bolt
