## Overview

Jim Dunlop Heavy Core Korn Guitar Strings 10-65 are a premium 7-string set engineered in collaboration with Korn’s Munky and Head. Featuring Heavy Core technology, these nickel strings deliver enhanced dynamic range, optimal tension for drop tunings, and exceptional tuning stability. Designed for metal and alternative players seeking studio-grade tone and durability, they are crafted in the USA to ensure consistent performance and a balanced, powerful sound.

## Description

Korn’s Head and Munky helped kick off the alternative metal movement with 7-string guitars and aggressive downtuned grooves. Searching for a way to evolve that sound and fully unlock the true potential of their instruments, they came to Dunlop. We worked closely with both players to build a set of strings around Heavy Core technology for increased dynamic range, optimal tension when drop-tuned, and incredible tuning stability. This is that set of strings—carefully tailored to the tonal and tactile dynamics of 7-string guitars. It’s the sound and feel that Head and Munky depend on whether they’re cutting tracks in the studio or throwing it down on stage.

Review: Excellent strings - Great sound!!! Holds a tune well so far.
Review: Literally the best string on the market for low tuning - I have probably have tried every single string company you can possibly name or imagine seeking tone for death metal, specifically drop A on a six string guitar with a hardtail bridge and non-active pickups. Ive also tried their Slipknot version both types, the Trivium version, the non-artist series heavy cores; all sorts of Dunlop string options and this hands down, is the best sounding string set they sell to date for metal. I just drop the high E string off and play the .65 to .13 sizes. They last forever, they hold great tone, I have low end, I have high-end, I absolutely love the response and feel of these strings. I will probably never put any other strings on my guitar ever. Best Bang for buck and I will die on that hill 😤
