Light 6-string set from XL series that was optimally designed for today's modern, shorter scale electric baritone guitars, but is also an excellent solution for deep, down-tuning on most standard electric guitars. It contains strings that are precision wound with nickel-plated steel onto a carefully drawn, hexagonally shaped, high carbon steel core. That means the strings are long lasting, with distinctive bright tone and excellent intonation, ideal for the widest variety of guitars and musical styles. This set comes in environmentally friendly, corrosion resistant packaging that ensures the strings are always fresh. The strings are made in the U.S.A. for the highest quality and performance. Gauges: plain steel - .013, .017; nickel wound - .026, .036, .046, .062.
