Heavy-gauge strings with heavy duty treatment.
Kerly Sinister Strings are nickel wound, heavy-gauge strings seasoned between -320F and plus 350F for 24 hours to reduce the micro-cracks that cause tonal loss and premature breakage. Thanks to the repetitive HOT/COLD tempering process, the micro-cracks close up, preventing the buildup of dirt and corrosion. Strength, sound, and string life are enhanced. Set of 6 medium-gauge guitar strings.
