RMV Tom Fell Deep Performer Clear Double-Ply 10 Inch. Double-ply drumhead, 10 inches, glued transparently at the edge. Sturdy head with a fat sound, ideal for rock and live applications. Deep Performer (2x7mil) drumheads consist of two equally thick layers with a 1-inch adhesive rim. They provide a controlled, deep tone and can be tuned quickly and efficiently. Due to the consistency of the low frequencies, they can be combined with other models. These are the preferred heads for drummers who play a heavy sound with consistent dynamics.
