The Classic Clear is a thin, sensitive, resonant snare side head. The High Performance version has special reinforcement where each end of the snare wire lies, which helps to prevent puncturing.
These have the look, feel and warm sound of a calfskin head. The American Vintage model has a slightly larger than standard hoop to allow an easy fit on most vintage drum shells. Both models are single ply.
Speciality heads for snare drums. "Genera" indicates a built in overtone control ring, "Dry" has vent holes added, "HD" means double ply. Power Centre has a dot either on top or underneath (reverse). Order reverse if you play with brushes.
