BLACK DIAMONDBlack Coated Phosphor Bronze
Designed for dramatically longer string life and to bring clarity to a guitar’s tone, all six strings in this set are treated with Black Diamond’s black coating for a balanced feel and full protection from hand oils and environmental decay.
These strings feature a polymer coating that’s intended to offer a smooth feel, windings that are almost self-cleaning and unaffected by perspiration, and tone that will outlast most conventional strings.
C.F. MARTIN & CO.Lifespan SP
The SP core wire in this set is engineered to resist breaking and for superior tuning hold with a rich tone and responsive attack. All six strings are treated with proprietary technology to help deliver the longest possible string life without sacrificing tone or feel.
CURT MANGANNickel Wound Coated
The proprietary in-house coating process for these strings, which was developed in 2008, is four-to-five times more resistant to tarnish and corrosion than an uncoated string, and was designed to not compromise tonal quality or alter feel.
