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! Fewer 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 lets them move freely, giving their tone some of the gloss associated with more responsive Phosphor Bronze strings.
