Elixir® Strings Nickel Plated Steel Bass strings with a NANOWEB® Coating took a year of intense research and feedback of 1000+ bassists. With the coating designed just for bass, these Nickel Plated Steel Strings offer enhanced grip, reduced finger squeak, and extended tone life. The tone is rich, rounded with greater clarity and heavier mid-range presence. While other 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. 4-String Gauges Available Include: 4-String Super Light/Long Scale Gauges: 040 060 075 095; 4-String Light/Long Scale: 045 065 080 100; 4-String Medium/Long Scale: 045 065 085 105; 4-String Medium/Extra Long Scale: 045 065 085 105; 4-String Heavy/Long Scale: 050 070 085 105; Custom 5th and 6th Nickel Plated Steel string singles available
