.009 .011 .016 .024w .032 .042 - set / E-Guitar Nickel-plated steel wound Hexagonal core All strings with K3 Coating Neon Multi-Colour coated Luminescent DR NEON HiDef SuperStrings - Super bright in day light, and with stage lighting. DR's NEON strings are so bright in appearance "they look like they are on fire." DR's NEON strings shine brightly under stage lights, and are 100% black light active so they glow strongly under UV lighting. And DR's NEON sound as good as they look. They look great and have an incredible sound. The strings last as long as a coated string should (three to four times as long as uncoated strings). All strings are coated with the patent-pending K3 Coating for improved performance and corrosion resistance.
