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 smooth full-range tone that's extremely popular with acoustic guitar players of all styles. In fact, 80/20 bronze strings are really popular with guitarists playing rosewood, ovangkol, and even maple guitars for the fullness and depth they provide. And with Elixir's Nanoweb coating, these 80/20 bronze keep their vibrant tone longer than conventional strings.
