Gary Clark Jr.'s tone on Bright Lights is a modern take on classic blues guitar. An SG through a Fender Vibro-King produces a warm, fat clean tone that breaks up beautifully when he digs in. The tone has more midrange warmth than a typical Fender clean, thanks to the SG's humbuckers. Clark uses a Tube Screamer-style overdrive for solo boosts, pushing the amp into rich, singing sustain.
