The DW 9002PC "LEFTY" Double Pedal is just what you need for reaction and speed. To create incredibly smooth, gravity-defying action, the 9000's Floating Rotor is not permanently affixed on a conventional drive shaft but is mounted on a free-floating drive shaft using friction-reducing ball-bearings. In addition, the patented Rotor can be infinitely adjusted using the Infinite Torque Adjustment for a variety of positions from center (Turbo-style) to eccentric (Accelerator-style), achieving the desired balance of power and precision in any playing situation. Furthermore, by moving the location of the Floating Spring from the end of the hex shaft to the center of the pedal, the vertical alignment of the moving parts is maintained and the indirect transfer and loss of energy is virtually eliminated - further optimizing the pedal's speed and power and precision.
