My brother is a luthier, a luthier who once repaired a guitar for Rod Stewart. So when he recommended Elixir guitar strings I gave them a try. The nano coating feels good to my touch and lasts sooo long. I recommend them to all my friends, hobbyist or pro.
The Reason: Uncoated strings do not have any protection from the direct contact with your fingers, and as gunk builds up in the string winding, the string is unable to vibrate as freely as when it was shiny and new.
Uncoated String Elixir® Strings
The pictures above are examples of what might happen to your strings after 15 hours or so of play. You can see why your uncoated string is sounding lifeless. Tiny bits of skin and dirt become trapped in the windings, and sweat and skin oils have caused the metal to corrode.
With Elixir Strings, the patented polymer coating covers the entire string and forms a barrier against tone-killing gunk.
A string is made of a metal core (usually steel), and includes a metal winding on the heavier gauges. As you play your guitar, bass, or other stringed instrument, the uncoated string will quickly accumulate oils, dirt, sweat, and bits of skin that get trapped between the windings. The lack of coating also hastens the corrosion of the metal, and the feel of the dead string begins to hamper your playing performance.
With Elixir Strings, a protective fluoropolymer coating is added to the string via a patented process. The coating forms a barrier between the string and the environment. Since the entire outer surface of the string is coated, the gaps between the winding are protected. As you can see in the photos, after just a few gigs, an uncoated string shows the debris and corrosion in the winding, while the Elixir String remains nearly pristine. Result: With Elixir Strings Players report with Elixir Strings their tone lasts longer than any other string, uncoated or coated. You’ll spend less time and frustration changing strings, and more time playing.
