DW 5002 Delta IV Turbo Double Bass Drum Pedal

The Accelerator™ (AD4) drive system offers an eccentric motion that creates an indirect relationship between the sprocket and the footboard, increasing the velocity of the pedal by shortening the length of the stroke. It is recommended for situations that require increased speed and sensitivity. The Turbo™ (TD4) concentric drive system maintains a direct relationship between the sprocket and the footboard to provide a solid, powerful, consistent feel and response.
