That's right, this is the one everyone's been talking about. It's simply amazing what a little -320¹ liquid nitrogen can do to a guitar string. If I were you, I'd put on a set and see what all the noise is about. Twice the tone and twice the life.

Blue Steel strings are the world's first and finest Cryogenic-processed strings. Blue Steel strings are a total breakthrough in string technology. Starting with the very finest quality materials, Blue Steel strings are frozen to minus 320 degrees Fahrenheit, held there for an exact period of time and then slowly and carefully brought back to their original temperature. This unique Cryogenic treatment realigns the molecular structure of the string, giving Blue Steel more highs and lows, a longer life, and greater ability to stay in tune. Blue Steel strings are available for acoustic, electric, and electric bass guitars, and come in all popular gauges.
