King, 89, has used various models of Gibson guitars over the years, and named each one of them Lucille.
In the 1980s, Gibson officially dropped the model number on the guitar he used last and most. It became a custom-made signature model named Lucille, manufactured exclusively for the "King of the Blues."
Some of his hits include "The Thrill Is Gone," which won him his first Grammy in 1970, "There Must be a Better World Somewhere" and "When Love Comes to Town," a collaboration with U2.
Last year, the bluesman suffered from dehydration and exhaustion after a show in Chicago, forcing him to cancel the remainder of his tour.
