Elixir is the brand that brought coated strings to the forefront of string technology. Coated strings repel the dirt and debris that collects under the outer winding. The debris dampens the vibration at the core, causing stings to lose sustain and diminishing fundamentals within the tone. The coating allows the player to get longer life from each set of strings! Now improved with hydrophobic treatments that repel moisture, coated strings can last up to five times longer than uncoated strings.
