With Elixir® Strings the tone lasts 3-5x longer than ordinary strings. This means you buy fewer sets of strings, change them less often, and trust that your guitar is ready to go when you are.
Elixir Strings is the only string that coats the entire string and not just the wrap wire. This prevents corrosion and contamination from accumulating on the surface and, most importantly, from collecting in the space between the windings.
