Jazz strings for electric guitar. Cryogenically frozen with a blast of liquid nitrogen, which tighten the molecules, minimizing microscopic gaps. This process removes transient frequencies that produce harsh highs and muddy lows, creating a more consistent string, with true tone and longer life. Precision wound with proprietary alloys specifically developed to deliver fantastic sound, and super-long lasting. Features set of six strings. String size: .012 / .015 / .026 / .034 / .044 / .054.
