All this and they still feel like traditional stringsElixir Nanoweb Acoustic String FeaturesGreat Sound that lasts 3 to 5 times longer than ordinary stringsBright tone and punch like that of non-coated stringsThe Same Feel you get from Traditional StringsWhat causes ordinary strings to go deadYou do. Every time you pick up your guitar and play, you leave tiny bits of dead skin, body oils, sweat, and all types of gunk loitering on your strings. Stuck between the windings (a space Elixir calls theCritical Zone of Tone), these contaminants dampen vibration and accelerate corrosion. The result Strings that are dead, rough and dirty.The Cure for the Common String.Elixir Strings are coated in a unique way to protect wound strings from your DNA and other contaminants. A flexible, strong, yet micro-thin polymer tube defends the Critical Zone of Tone from invading enemies. Nothing (including the coating) gets between the windings. The result Strings that sound and feel their best three to five times longer than ordinary strings.The Choice is YoursElixir Strings are available in two different flavors. Both deliver the same long life, but differ in tone and feel.
