Multi-Annular Ring Drums
are made using the patented multi annular shell construction where rings are cut from plywood then are glued as they are stacked on top of each other. Plywood being layers of perpendicular stacked wood plys , offers a  stable construction method to prevent the shells from losing the cylindrical shape. It is not known  how much of a sonic impact this method  has but I think that the look is very different and cool. My favorite types of plywood to use are Baltic Birch, Acoume  Mahogany and Colorwood because they have little or no voids in the wood.

Drums shells can be custom ordered from a choice of available wood in a range of diameters, depths and thicknesses.  Order complete drums or just shells.
