Lazer DHB-13 Single Ply Drum Batter Head 13"

Your drumheads (and what you do with them) are the biggest things affecting your drum sound. With all other things equal, and with an at-least okay drum kit (i.e. round drums, good bearing edges, etc.), it's the drumheads that count the most.

The drum head's thickness is also important: thinner, single-ply (ply means layer) heads have a sensitive response, with bright, resonant sound and complex overtones.
