Made to withstand 3 times more than conventional strings, American company Dean Markley used the pioneering method of "cryogenic" to create a set of strings for Electric Guitar rich in tone, with great presence and intensity while also providing excellent playing feel with strong sustain. The "cryogenic" method cleans the "harsh" high and low frequencies that distort the sound of the guitar, offering greater durability and better tone with rich and clean harmonics. They contain 8% nickel/nickel-plated with hex-core wire.
