Built for modern heavy music, the Dunlop Heavy Core 7-String 10–65 set delivers the tension, clarity, and tuning stability demanded by today's down-tuned players.
Developed in collaboration with Head and Munky of Korn, these strings are engineered to maintain a tight, focused low end without sacrificing feel or playability. By carefully balancing tension across all seven strings, the Heavy Core design provides excellent note definition, powerful attack, and consistent response, even under aggressive picking and extended-range riffing.
Whether you're playing drop tunings, progressive metal, djent, or hard rock, this set offers the stability and articulation needed to keep complex chords and fast rhythmic passages sounding clear and controlled.
Each pack also includes a custom Dunlop Tortex® guitar pick designed in collaboration with Head and Munky.

Black Crane Notes
For players who spend most of their time in drop tunings, string tension is just as important as gauge. The Heavy Core series addresses this by delivering a firmer, more controlled feel where it's needed most, helping maintain tuning stability and articulation without making the strings feel stiff.
The result is a set that performs exceptionally well for modern metal while remaining comfortable enough for everyday practice and performance.
