This bundle pairs two sets of 7-string electric guitar strings from Dunlop's Heavy Core line, developed in collaboration with prominent nu-metal and metalcore artists. The first set was created with Korn's Head and Munky to unlock the full potential of their downtuned 7-string tones and aggressive playing styles. The custom 10-65 gauge combination delivers increased dynamic range, optimal tension when drop tuned, and incredible tuning stability. The second set was handpicked by Trivium's Matt Heafy and Corey Beaulieu to provide peak performance when tuning down. The 10-63 gauge mix focuses on stable tuning, balanced full dynamic range, and vivid highs and lows. With a set tailored to nu-metal and another built for metalcore, this bundle gives you the signature strings of bands from two major metal genres. The collaboration behind each set ensures they capture the exact tones, tension feel, and tuning stability demanded by Korn and Trivium themselves. Together they allow exploring the sonic possibilities of downtuned 7-string playing across styles, from punishing grooves to intricate riffs.
