NGA-12 NEON Hi-Def Phosphorescent Green Acoustic Strings Medium. NEON is the second in DRs SuperStrings series. Now available for acoustic guitars, NGA-12 Neon HiDef Phosphorescent Green Acoustic Strings Medium are super bright in day light, and with stage lighting. DRs NEON strings are so bright in appearance "they look like they are on fire." DRs NEON strings shine brightly under stage lights, and are 100% black light active so they glow strongly under UV lighting. And DRs 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. Gauges: 12-16-24-32-42-54
