Herman Li (DragonForce) used vibrato in almost all his guitar solos, producing several unique sound effects. "The Elephant" (first heard by Eddie Van Halen in the mid 1980s), where he turns the volume down, plays a note, raises the pitch with the arm and turns the volume up at the same time, creating a sound similar to an elephant's trumpeting. He also removes the arm and strums it across the strings, creating the "Pac-Man" noise, or runs it up and down the string, creating a "ghost noise". In the song "Cry For Eternity" he combines these, playing four pac-man noises, followed immediately by an Elephant noise.
