Medium handmade 6-string set for electric guitar from Red Devils series that feature the K3 Coating – first coating that “sounds as good or better than uncoated strings” as players report. DR's new, remarkable, proprietary and patented K3 Technology Coating is the first coating that makes no apologies and no excuses for not delivering sound equal to uncoated strings. These strings have more volume, less unwanted overtones, greater clarity and articulation then standard, uncoated strings. Yet, they provide the same protection due to corrosion and perspiration as well as increased tone life that coated strings are known for. Gauges: .010, .013, .017, .026, .036, .046.
