For decades, working drummers have relied on DW 5000 series pedals to perform their best, gig after gig. Over the years, 5000 series pedals have remained true to their original design, but with innovative updates that have made them even more rock solid than before. The DW Delta III Accelerator Single Bass Drum Pedal is ideal for speed and sensitivity. The indirect relationship between the sprocket and the footboard increases the velocity of the pedal by shortening the length of the stroke. The Tri-Pivot Toe Clamp ensures firm connection between the pedal and drum. The DWCP5000AD4 also features a new Non-Skid Rubber Grip for the base plate, and Dual Bearing Spring Rocker that improves smoothness. The Drum Center of Portsmouth is your DW headquarters.
