Trivium's Matt Heafy and Corey Beaulieu need gear that keeps up with their creative drive. That's why they came to the Dunlop String Lab and designed their own set of Heavy Core® Strings, with each gauge handpicked to keep notes stable and focused at lowered tunings while offering a full dynamic range that's balanced with vivid highs and rich lows. This set gives Matt and Corey the freedom to create the music they love with peak performance and playability.
