These CR-GBM Medium Sub-Zero Boomers from GHS are roundwound strings for electric guitars made with a quality steel core wire wrapped in a round, nickel-plated cover, and then cryogenically treated with liquid nitrogen.
The strings are frozen down to a temperature of -300°F and gradually restored to room temperature, a process which imparts the strings with increased brightness, heightened resistance to corrosion, and greater tuning stability.
Designed for heavy metal, rock, country, blues, and pop styles, these strings produce a bright, long-lasting tone, with the gentle feel of nickel.
