Elixir Strings Acoustic 80/20 Bronze Bass Strings with NANOWEB Coating deliver the crisp, lively tone and feel similar to traditional 80/20 bronze strings but with the advantage of extended tone life. With less hassle and expense of frequent string changes you enjoy more time making music. While other acoustic 80/20 bass strings lose their mojo fast due to dirt and debris, Elixir Strings is the only coated string brand to protect the entire string with an ultra-thin coating, keeping gunk out of the gaps between the windings. No wonder from the stadiums to the street, Elixir Strings players tell us their tone lasts longer than any other string, uncoated or coated. Single String Gauges Include 045, .065, .080, .100, .125
