Bass drum head in 22" size, is made from a single ply of 12-mil Mylar blended to produce the full, rich and vintage tone of calfskin. The Externally Mounted Adjustable Damping system - or EMAD - boosts attack while shortening sustain. Jazz, funk, rockabilly, classic country, and any other genre that prizes richness of sound over volume and punch will benefit from Calftone.
