Cleartone Strings is a guitar string manufacturer developed under the Everly Music Company, an outfit founded by Phil Everly of the Everly Brothers. Phil and his son Jason began deconstructing existing strings in the late 1990s with the goal of building a more durable product, launching Everly Strings in 1998 and introducing the Cleartone line in 2008 after years of R&D into a proprietary string treatment. The company manufactures its strings in the United States and operates out of West Bountiful, Utah.

The Cleartone catalog is built around its patented "No-Feel Coating," a micro-thin treatment marketed as extending string life several times longer than uncoated strings without dampening tone or adding a slick texture. The product range covers Phosphor Bronze acoustic sets, Nickel Plated electric sets, the Heavy Series for drop tunings and extended-range guitars, the Power Series, Sevilla nylon/classical strings, and bass strings. Cleartone also produces Star Picks, straps, and signature string sets developed with artists including Chevelle and Atreyu.

Everly Music is led by Jason Everly and produces several related brands alongside Cleartone, including Everly Strings, Sevilla, RED Brand Strings, Star Picks, and Postal Monkey Cases. Cleartone is positioned in the coated-string market alongside competitors such as Elixir and D'Addario XS, with reviews in outlets like Premier Guitar and Guitar World focusing on its longevity claims and natural feel.

Cleartone has 26 products cataloged on Equipboard, including Strings and Picks & Pick Holders. Their gear is featured by 16 artists, with the strongest followings in Rock, Metal, and Folk, World, & Country. Notable users include Dave Mustaine, Glenn Fricker, and Rob Scallon.
