Product description These Elixir strings capture this uniqueness and extend their length 3-5 times over traditional strings. This means you buy fewer strings, change strings less often and know your guitar is ready to go. Available in acoustic and electric strings, all strings feature Elixir Strings' patented NANOWEB or POLYWEB coating and rust-resistant plated plain steel technology. Elixir strings are the only strings that cover the entire string and not just the wound wire. This prevents corrosion and impurities from accumulating on the surface and, most importantly, in the spaces between the windings. With a vision to change the world one step at a time, we set out to develop treatments for common strings that would provide great tone for longer, keep them clean and smooth, and keep your strings inspired by your playing. p> After experiencing Elixir strings, it's hard to go back to your old ways. Of course, you can save money by buying fewer strings. 16002 Elixir Acoustic Nanoweb Phosphor Bronze Ultralight Guitar Strings 010-047 String Gauge - 010 014 023 030 039 047 16027 Elixir Acoustic Nanoweb Phosphor Bronze Custom Light Guitar Strings 011-052 String gauge - 011 015 022 032 042 052 16052 Elixir Acoustic Nanoweb Phosphor Bronze Light Guitar Strings 012-053
