Dunlop Heavy Core® electric guitar strings are made with great pride in Benicia, California and specially designed for the player that plays in dropped or lowered tunings.
Our Heavy Core strings 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.
The next time you open up a pack of Dunlop guitar or bass strings, you will notice we’ve done away with the plastic bag and desiccant pack in favor of new VCI (Vapor Corrosion Inhibitor) paper envelopes. These envelopes have VCI technology built into the paper itself, creating a barrier of protection around the string and keeping out moisture and rust. VCI is invisible and leaves no trace on the string. Dunlop Strings come out of the package as fresh as the day they were made.
