Product DescriptionA controlled sound but with resonance and sensitivity at all tuning and dynamic ranges, EC Snare head combines two-plies of film (6.5mil external, 10mil internal) with Evan's 'Edge Control' technology to eliminate the mid-range frequencies that muddy up the mix, leaving crisp highs and deep lows. The reverse dot version lends added durability and accentuated attack without choking the overall sound.From the Manufacturer EC Reverse Dot Snare Series Overview Evans EC snare heads feature two plies of film. The combination of a 7mil top ply and a 10mil bottom provides a controlled sound but with resonance and sensitivity at all tuning and dynamic ranges. Sound Shaping Technology (SST) rings on the underside reduce unwanted frequencies and enhances attack. The Reverse Dot lends extra durability, focus and attack in the center.
