These nickel wound strings are designed with a special core-to-wrap ratio so players can maintain tension and tonal focus when tuning below standard.

Dunlop Heavy Core Strings are made with great pride in Benicia, California and specially designed for the player that plays in dropped or lowered tunings. They incorporate a unique core wire and proprietary wrap ratios to offer players the ability to really dig in while retaining a tight low end, focused midrange and smooth top-end when playing clean or distorted.
