Coated : One of the Six Factors for Guitar String Tone and Feel

Coating refers to the process of adding an extra polymer protective layer to either the string winding, the core wire, or both. Most modern string sets are coated as it extends the lifespan of the strings and provides better protection against sweat.

In 1997, the Elixir company revolutionized the guitar string industry when they introduced the entirely new concept of “coated strings”. By covering strings with a micro-thin polymer coating, a barrier is created that protects the metal from damaging substances such as oil, sweat, dirt, and skin. As a consequence, the strings last several times longer than non-coated strings.

However, despite these advantages, Elixir strings are not beloved by everyone. According to their critics, there is a slight loss of brightness and sustain as a result of the coating.
