Elixir ATTUNE Strings Elixir's most uncoated coated strings to date. The sound tends to be dark and mellow. It has a unique "coating-like" feel to the touch. Some players believe these elements are inherent to coated strings. Elixir Attune Strings challenges such preconceived notions. Under the high added value of long lifespan, the existing lineup has created tonal differences by varying the thickness of the coating. However, with Attune, a completely different and unique new coating material has been adopted, and the research and development team repeatedly tested and refined prototypes. The innovation took many years, and more than 100 prototypes were tested before the product was finally brought to market. The resulting Elixir Attune Strings are the closest to uncoated strings among all of Elixir's coated strings to date. Thanks to our unique new coating material, Elixir has succeeded in combining the most durable coating in Elixir history with a bright, clear tone and natural touch that feels "as if it were uncoated." Acoustic guitar players, regardless of their playing style, will now be able to access highly durable strings without sacrificing tone or feel.
