ELECTRIC GUITAR STRINGS LIGHT: .009 .011 .016 .024w .032 .042 It's simply amazing what a little -320º liquid nitrogen can do to a guitar string! Blue Steel strings are the world's first and finest Cryogenically-processed strings and represent a huge scientific breakthrough in string technology. Starting with the very finest quality materials, Blue Steel strings are frozen to minus 320 degrees Fahrenheit, then held there for an exact period of time. Now that's cool! Then they are 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 a greater ability to stay in tune. Twice the tone and twice the life but at a ridiculously low price. That's StringItUp! for you! DM-2552$5.67 Cryogenically Frozen
