Mapex Quantum Mark II Drums on Demand Series Natural Shale Bass Drum 20 in.

The Mapex Quantum Mark II Drums on Demand series Natural Shale bass drums offer superior performance for your marching ensemble. These drums are part of the Mapex Drums on Demand program, created to deliver a durable premium-wrapped shell finish without long manufacturing production times. Based on the most popular school color combinations, these durable and attractive wrap finishes complement both traditional and contemporary style marching arts uniforms.

Constructed with a consistent 14" shell depth across all drum sizes, each bass drum features a six-ply maple shell, the overall thickness is only 5.8 mm, with 2.4 mm birch reinforcement edge rings for added shell integrity. The birch reinforcement edge ring incorporates the SONIClear bearing edge, designed to allow the drum head to lay flatter against the shell to provide a warm and rich resonant tone. Specific number of featured air vents on each size drum allow for a consistent focused tone and attenuated sustain. The externally adjustable eyebolts allow for easy height adjustment without needing to remove drum heads so you can adjust the drum to fit the player easily. The Quantum Mark II bass drums are available with aluminum alloy hoops and gloss chrome hardware finish.
