The Evans G1 Coated series is made from 1 layer of 10mil and provides great clarity, sustain, sensitivity and durability. This drumhead has an open and expressive sound. In lower tunings, the natural sound of the drums is additionally emphasized. The Coated versions deliver more warmth, focus and depth than de Clear versions. Evans 360 technology is applied to improve a "level playing surface". The design ensures evenly distributed contact with the drums' hoops for easy tuning, greater pitch range and optimum sound quality. Evans has been innovative in the production and design of drumheads for more than 60 years. They were also the first to market synthetic drumheads. Evans is known worldwide for their quality, consistency and their intention for solving drummers' problems. All heads are made in the USA.
