DR Strings Dragon Skin strings have a proprietary patent pending coating from K3 Technology Coating that makes them the first coated strings that "sound as good or better than uncoated strings."
DR's K3 Technology Coating is the first coating that makes no apologies and no excuses for not delivering sound equal to uncoated strings. Players say that these strings have more volume, less unwanted overtones, greater clarity and articulation than standard, uncoated strings. Yet, they provide the same protection from corrosion and perspiration as well as increased tone life that coated strings are known for.
DR Handmade Strings combine old fashioned craftsmanship with the very finest American made materials.
