Setting the standard for power and resonance, Challenger bass drums are crafted for today's contemporary marching bands and drum corps. Designed to drive a drum line, all multiple pitched bass drums are made with 6-ply Birch shells with high-tension long lugs. Cortex laminant finishes are integrated into the molding process of shells and hoops for increased strength and reduced weight. Laminant hoops enhance appearance while heat-treated claw hooks and key rods are designed for strength and durability. All bass drum include one pair of Ludwig aluminum shaft bass drum mallets.
