The Stainless Steel Strings have aggressive, growly, concentrated mids with a punch that cuts through the mix. The NANOWEB Coating for bass provides a smoother, more natural feel while extending tone life. It took more than a year of R&D and working with over 1000 bassists to develop Elixir Strings for Bass. The NANOWEB Coating on our Nickel Plated Steel and Stainless Steel Bass Strings is more durable, delivers unparalleled tone life and also raises the bar in tone, feel and response. Bass players tell us that Elixir Strings retain their tone longer than any other string - uncoated or coated.
