The Dunlop R. Willy Sangria Large Slide Signature is a testament to the iconic style and distinctive sound of rock 'n' roll. Reverend Willie G., also known as BFG, is synonymous with a look and sound that are instantly recognizable. Dunlop's collaboration with the legendary Billy Gibbons of ZZ Top—a band that has been a powerhouse since 1969—has produced this signature slide. Gibbons' sound, often referred to as "Rio Grande Mud" or "Hot, Blue, and Righteous," is epitomized by his own description: "just meat, on metal, on wood."
