Medium 6 string set for acoustic guitar from NEON series with super bright K3 multi-colour coating that delivers clear, bright and musical sound. Strings are bright in daylight and under stage lighting, 100% black light reactive and they glow strongly under UV lighting. They last longer as any other coated strings – three to four times as long as uncoated strings, but sound as good as uncoated strings. The strings are made with steel hexagonal cores and special multi-colour nickel-plated steel windings. Gauges: .012, .016, .024, .032, .042, .054.
