The Reso 7 is a new 7 mil coated resonant head from Evans. The idea is to control the resonance of the drum from whence the resonance comes – which is, of course, from the resonant head. This way you can reduce or eliminate the need for Moon Gels or ye olde wad-o’-gaff-tape to keep the ring down.
So if you’re sick of the ring, this might be just the thing.
