This Trick black-finish floor tom drum was cast from Trick"s special resonant alloy--AL13. Trick"s material comes certified from the mill, and guarantees the same hardness and thickness of every Trick drum shell to 1/8" or 3.175mm. AL13 provides the pureness of tone, resonance, durability and performance that comes standard with every drum Trick builds. Trick"s design simply utilizes the natural law of physics, allowing all Trick Drums to resonate to their full potential.Manufactured from the same AL13 shell as Trick"s drum sets, Trick tom drums feature lathe-cut bearing edges, solid machined aluminum tuning lugs, and electro finishes. Trick tom drums provide the player with amazing sensitivity, projection and cutting power.Trick Drums also feature bearing edges that are lathe-cut to an exacting double 45. This allows for superior attack, sensitivity, and faster tuning.
