A fresh set of batter heads can reshape the feel and response of an entire kit, and the EVANS 6-piece Pro Drumhead Upgrade Pack brings kick, snare and four tom positions together in one coordinated set. The 22" EMAD Clear bass head uses a single 10-mil ply with EMAD foam rings to adjust attack, focus and sustain, while the 14" HD Dry snare head combines 5-mil and 7.5-mil plies with a 2-mil control ring and precision-drilled dry vents to help control unwanted overtones. A Rock-size G2 Clear tom pack covers 10", 12" and 16" diameters, while a bonus 14" G2 Clear adds a fourth tom head. All four use two plies of 7-mil film for balanced attack, controlled sustain and full low-end response, while Level 360 technology across the included heads supports easier tuning and an extended pitch range.
