Paul Daniel "Ace" Frehley is an American musician and songwriter best known as the former lead guitarist and founding member of the rock band Kiss.
Guitar World magazine ranked him as the 14th Greatest Metal Guitarist of All Time. His solos often incorporate the minor pentatonic scale and the use of vibratos. Frehley is also known for the use of many "whimsical" guitars, including a Gibson Les Paul guitar that emits smoke from the neck humbucker pickup and produces spinning pyrotechnics, and a custom Les Paul that emits light based on song tempo.
