Custom 6 string set for electric guitar from Cobalt Electric Slinky series that was engineered to maximize output and clarity and represent the latest innovation in string technology. Strings provide an extended dynamic range and better harmonic response. Plain strings are made of specially tempered, tin-plated, high-carbon steel, producing a well-balanced tone. Wound strings are made from cobalt plated steel wire wrapped around a hex-shaped steel core wire and deliver increased sustain. Cobalt is also more flexible than nickel and the most magnetically active string alloy, therefore provides a stronger relationship between pickups and strings, plus is more sweat and moisture resistant. Strings are precisely manufactured to the highest standards and most exacting specifications to ensure consistency, long life and optimum performance. Gauges: .011, .014, .018, .028, .038, .048.
