Evans E-Rings are an easy way to control overtones from your drumhead. Overlay them on top of the drum and they flatten and round out the drum's sound making it easier to tune. Save time in the studio and get killer snare sound. A great value too, because they're reusable.
The E-Rings are available in two configurations. The fusion pack consists of 10", 12" and two 14" rings, while the standard pack offers 12", 13", 14" and 16" rings.
