“After the manufacturing of our natural uncoated string, the Black Diamond strings are put into a high-pressure spray booth which sprays a micro mist. Our proprietary environmentally safe coating adheres to the outer wound strings, then seeps into the crevices.

Our treatment not only adds to the life of the strings, but makes for a smoother feel. Although a micro coating, these strings sound natural. Available for electric and acoustic guita.” – Black diamond
