Elixir OPTIWEB Coating electric guitar strings deliver the performance of a natural string with a crisp tone, natural feel, and playable grip. This lightweight coating allows the string to vibrate with less damping, offering a firm grip for better control over bends, vibrato, and sustain. Elixir Strings coat the entire string, protecting the outer surface and the gaps between windings from tone-deadening gunk. Anti-Rust Plating on plain steel strings ensures longer tone life for the entire set. These 7-string electric guitar strings are constructed with nickel-plated steel wrap wire and provide the crisp tone of an uncoated string. The coating technology protects against corrosion and debris, extending tone life significantly longer than other brands.
