Elixir Acoustic Nanoweb strings don't just sound great; their micro-thin coating keeps them sounding great for a lot longer than average strings. If you want to keep your guitar tone consistently great day in and day out, put on a set of Elixir Acoustic Nanoweb strings. Their coating actually cuts down on unnecessary finger friction. You'll be amazed at how long they last! Less string changes means having to buy strings less often. Elixir's 80/20 Bronze strings are made of 80% soft copper and 20% durable zinc, presenting a smoother, mellower tone than Phosphor Bronze acoustic strings. They tend to assume a warmer glowing tone, but the ultra-lightweight Nanoweb™ coating gives lets them move freely, giving their tone some of the gloss associated with more responsive Phosphor Bronze strings.

Extended Tone Life When Elixir Strings burst onto the string scene in 1997, our patented coating technology was unique – and still is. Other strings are sabotaged by debris and skin particles, which get trapped between the windings when you play, contaminating your strings and killing your tone. With Elixir Strings, the coating acts as a physical barrier between the string and its damaging environment. Elixir Strings is the only brand to coat the entire string – protecting not only the outer string surface, but also the gaps between the windings. Result: Elixir Strings players report their tone lasts longer than any other string – uncoated or coated. Differences Between POLYWEB , NANOWEB and OPTIWEB Coatings Elixir® Strings are available in two distinct flavors of protective coating. Both feature the same patented protection and extend tone life, but differ in tone and feel. Some players prefer POLYWEB Coating and others NANOWEB Coating. It's a personal preference!
