With Vagabonds, Virgins & Misfits, Campbell and the Dirty Knobs (named after tech slang for a broken amp dial) have made the most expansive and dynamic album of the Dirty Knobs’ one-of-a-kind ride. The group was founded in 2000 by Campbell as a writing and club-date project outside the Heartbreakers. The group finally got on record with 2020's Wreckless Abandon and 2022's External Combustion, both made with George Drakoulias and Martin Pradler, who return to co-produce the new album with Campbell. Those LPs, Campbell says, were the Knobs “trying to find our way as a rock & roll band.” “Now it’s down to great songs,” adds Campbell, “the depth in the lyrics and chords.” He recalls something Petty once told him: “Tom said, ‘I love the English language. There’s so much you can do with it.’ I'm discovering that, too. Looking for rhyme schemes, the right word. At first it was a struggle. Now that door has opened,” Campbell says. “I’ve turned a corner” on Vagabonds, Virgins & Misfits. The Dirty Knobs are “still a rock band but growing into different feels.” In additional to Campbell, The Dirty Knobs features fellow Heartbreaker Steve Ferrone on drums, Chris Holt (Don Henley) on guitar and Lance Morrison (Don Henley) on bass.
