Dunlop strings are designed, developed and manufactured at our state-of-the-art strings factory in Benicia, CA. Armed with the latest machinery, Dunlop string designer Les O'Connor, formerly of DR Strings and Black Diamond Strings, led the Dunlop design team to bring the Dunlop strings vision to life. Without being tied to a '60s string formula, Les took a modern and scientific approach to string design. With critical feedback from top touring artists, Les was able to design a string that met modern guitar player's needs. Dunlop Strings use traditional high quality materials and metals to produce non-coated guitar strings in standard gauges. In addition, innovative hybrid wrapping techniques and custom core-to-wrap ratios produce a superior low-tension string. All Dunlop strings are balanced set to set and come in corrosion inhibiting packaging that keeps them fresh.
