## Description

KQXS7-1160, Custom Heavy NPS Electric 7 String Gauge .011, .015, .022P, .032, .044, .054, .060.Feeling a heavy gauge string under your fingertips gives you extra power while cutting through with an unmistakable growl and chunk. These tonal flavors are a necessity for hard hitting, drop tuned riffs and passion driven playing. Sinister Strings are seasoned by a patented process between minus 320F and plus 350F for 24-36 hours. The repetitive Hot/Cold Tempering process causes the metal to expand and contract, which reduces the microcracks that cause tonal loss and premature breakage. The result is a Long-Life Guitar String.
