Black Coated Electric Guitar Nickel by Black Diamond USA

Black Diamond 400B Electric Guitar Nickel Black Coated Utilizing the finest high-carbon steel core wire, our process for crafting guitar strings ensures unparalleled quality. Our proprietary construction features a carefully balanced core-to-wrap ratio in combination with precision tensioning to create ideal playing dynamics that bring out the best sound from any instrument. Black Diamond Strings® offer unparalleled longevity, thanks to a protective black coating that fends off premature wear caused by hand oils. With this added protection comes the ability for musicians to get up to three or four times more playing time out of their instrument – and easy-to-spot signs when it's finally time to replace them! For maximum coverage, every single one of the strings is equipped with an even coat; ensuring consistent feel across your instrument. MADE IN CALIFORNIA
