Dunlop and Trivium Unveil Heavy Core Strings

Trivium's Matt Heafy launches a series of handpicked gauges for a full dynamic range and exceptional stability when downtuned.

Handpicked by Matt Heafy and Corey Beaulieu, Heavy Core Trivium Guitar Strings keep notes stable and focused at lowered tunings while offering a full dynamic range that’s balanced with vivid highs and rich lows. Coming in 6-and 7-string sets, these strings give Matt and Corey the freedom to create the music they love with peak performance and playability.

“Since the beginning, Trivium has used Dunlop Strings—the exact same custom set you are holding in your hands,” say Corey and Matt. “We have vastly different equipment and playing styles, but the one constant between us is—and has always been—Dunlop’s world-class strings.”
