Evans™ EC2™ series features two plies of 7mil film with optimized attack, tone, length of sustain and ease of tuning for each size head. The Sound Shaping Technology (SST™) Edge Control ring mounted on the underside delivers an extremely well balanced and pre-EQ’d sound across the full kit by varying the size of the ring for each different head size.
The new Evans EC2 SST (Sound Shaping Technology) heads use an ink ring that is painted onto the head rather than the glued on metal ring. The new ink ring allows Evans to control the ring thickness and density as well as the width. This allows them to really target select frequencies on each size and open up the tuning range. The character of each drum really comes out.
