Every set of Dunlop acoustic guitar strings delivers brilliant and rich tone for a dynamic and expressive acoustic experience. The finest wire combined with precise construction produce versatile strings durable enough to withstand hard strumming--and responsive enough for delicate fingerpicking. Chords ring out with great clarity, bass notes growl, and harmonics pop and sing. Dunlop's formula creates strings that are exceptionally long-lived, they break-in fast and stay bright so you can spend more time playing and less time changing your strings.
