Maple offers a warm sound with full sustain and outstanding projection. Our original Air Seal System shells feature select maple wood cut in plies, positioned with staggered diagonal seams, and sealed together with evenly distributed air pressure. This process ensures that every drum shell is in round and of uniform thickness. It also provides the shell with superior tone quality and durability. Floor tom and tom shells use a 7-ply design. Additional plies in the 10-ply bass drum shells help produce a low fundamental tone.
