Gauges: 11, 15, 22, 30, 40, 50. DR Strings NEONs are super bright color-coated strings that sound clear, bright and musical. These Multi-Color Medium-Lite Acoustic are an excellent idea for those learning to play or just wanting to add pizazz to their rig. It's easy for players to fall in love with the bright color that matches their remarkable sound. Super bright in daylight and under stage lighting, DR’ Strings NEONs are 100% black light active and glow strongly under UV lighting. These strings will last you as long as a coated string should (three to four times as long as uncoated strings) maintaining a sound that is not only good, but better than top-quality uncoated strings.
