The Modern Vintage II Bass Drumhead with Felt Strip is a 2x7mil, two-ply, bass drumhead that features Aquarian's proprietary Vintage coating that simulates the look, the feel, and the warm sound of a calfskin head. The "Old School" vertical felt strip adhered to the backside of this kick head adds that Swing Era look and sound to the Bass Drum. No extra muffling required. The two 7mil vacuum-molded design adds low end and clarity while the felt strip adds just the right amount of tonal control allowing this head to work equally well as either a batter or resonant head.
