Pearl P2050C Eliminator Redline series double pedal with case. Pearlâ€™s original PowerShifter Eliminator was a giant leap ahead in bass drum pedals. The worldâ€™s only pedal featuring the patented Interchangeable Cam System, Eliminatorâ€™s virtually unlimited tunability lets the player lock in totally personalized feel, power and speed. The Eliminator: Redline is the next step forward. Like having four pedals in one, Redline fuses the stunning power and flexibility of the original Eliminator with the fluid speed of our Demon series pedals. With a host of radical improvements, Eliminator: Redline helps unlock perfect feel by locking in a cam, further pushing the boundaries of bass drum performance.
