The flagship of the DW pedal line-up, 9000 pedals feature patented innovations such as a free-floating rotor-drive system, rotating swivel spring and infinitely adjustable cam allowing a more direct transfer of energy that optimizes the stroke for more power and precision. The DW Infinite Adjustable Cam allows the pedal to be easily set from Accelerator™ to Turbo™ Drive or anywhere in between. DW machines its Precision Universal assemblies in-house from aircraft-grade aluminum to meet strict tolerances. The result is a double pedal with smooth, effortless action. It's no wonder pro-drummers select this as their number one choice. Try the DW9000PB Single Bass Pedal today at OXYGEN MUSIC.
