The Pearl Demon XR Bass Drum Pedal is your direct path to rapid fire bass drum performance. The product of a two year research and development collaboration with drummer Gorge Kollias, the Demon XR (for Extreme Rebound,) essentially rewrites the playbook on high-speed bass drumming. Featuring a stripped-down, machine shop design for lightweight feel and a faster stroke, its secret lies in the enhanced rebound action of the XR High-Tension Spring. This accentuates rebound, making repeated strokes in the most extreme musical situations effortless. Feel can be tailored with a quick change to the included Standard Spring for more traditional feel. Its XI Beater contacts the head with a high-impact "riccochet" that further enhances accuracy and high tempo technicality. • Premium Direct Pedal Drive with Machined Aluminum Design • Precise, resistance-free playability • Changeable Extreme Rebound High-Tension or Standard Feel springs • Extreme Impact Beaters accentuate rebound and deliver unique sound • Sleek footboard for smooth playing surface • Designed in cooperation with Gorge Kolias.
