We're honored to officially partner with D'Addario, whose guitar strings we've used for many many years. We grew up seeing our favorite guitarists in posters and magazine ads for D'Addario strings, and now, to become official D'Addario artists ourselves is somewhat surreal. For those who are curious, Ryan plays EXP12s on his guitar and EXP75s on his mandolin, while Cameron uses EJ17s on his guitar and EJ88Ts on his ukulele.
