Jimmy Herring’s main guitar with Widespread Panic is a custom-built Paul Reed Smith with Lollar Imperial pickups, two volume controls and a single tone control. He favors jumbo frets with medium action for more clarity and definition, and strings them up with D’Addario .010 sets. The back of its headstock bears the legend “Custom built for Jimmy Herring,” and is signed by Smith. His backup axe, which also has Lollar Imperials, is a David Grissom signature PRS that he mostly pays in drop D.
