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. As Joey Clemment from Selena Gomez said, "Yeah they look great, but they sound incredible!"NEON is the first coated string to make no apologies. 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.K3 Coating CareThe K3 coating on EXTRA-life strings is designed for use with standard picks and fingers.
