NGA-11 NEON Hi-Def Phosphorescent Green Acoustic Strings Medium-Light. NEON is the second in DR's SuperStrings series. Now available for acoustic guitars, NGA-11 NEON Hi-Def Phosphorescent Green Acoustic Strings Medium-Light are super bright in daylight, 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. While NEON lasts as long as a coated string should (three to four times as long as uncoated strings) they sound as good, or better than uncoated strings. Guages: 11-15-22-30-40-50.
