## Overview

Jim Dunlop Heavy Core Korn Guitar Strings 10-65 are precision-engineered nickel-coated strings designed in collaboration with Korn’s Munky and Head. Tailored specifically for 7-string guitars, they deliver exceptional tuning stability, dynamic range, and tonal balance, especially optimized for aggressive drop tunings. Made in the USA, these strings combine durability with professional-grade sound, making them the go-to choice for metal and alternative guitarists seeking studio and stage-ready performance.

## 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: 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 😤
Review: Beefy guitar strings! - I was trying to find a set of strings for my 7 string guitar with a heavy bottom as I was trying to experiment with drop G tuning and they have been doing the trick so far. I love the play and feel of them and they stay in tune pretty well. I have a floating tremolo bridge which has its own set of challenges as it is a constant battle for precision tuning but they are as good as I was hoping. I loved them so much I decided to buy a few packs as it is recommended to stick with the same brand and gauge for maximum durability and stability.
