Product Description These Elixir strings capture the unique and extend it 3 to 5 times longer than conventional strings. This means you buy fewer strings, change them less often, and have the assurance that your guitar is ready to go when you are. All available strings, whether acoustic or electric, feature Elixir Strings' patented NANOWEB ® or POLYWEB ® coating and stainless steel plated technology. Elixir Strings is the only string that covers the entire string and not just the winding wire. This prevents corrosion and contaminants from accumulating on the surface and, most importantly, from accumulating in the space between the windings. With the ambition to change the world one set at a time, we are committed to developing a cure for common strings that offer fantastic sound for a very long time. Strings that remain clean and soft. Strings that always make you want to play. After experiencing Elixir® Strings, it's hard to go back to the old way of life. It is certain that the fact that you need to buy fewer string sets will save you money. 16002 Elixir Acoustic Nanoweb Phosphor Bronze Extra Light Guitar Strings 010-047 String Gauges - 010 014 023 030 039 047 16027 Elixir Acoustic Nanoweb Phosphor Bronze Custom Light Guitar Strings 011-052 String Gauges - 011 015 022 032 042 052
