Mike Campbell & The Dirty Knobs

The Dirty Knobs While in the Heartbreakers, Campbell was lead singer and guitarist with a side band, the Dirty Knobs, with guitarist Jason Sinay, drummer Matt Laug, and bassist Lance Morrison. "It's rougher-edged ," Campbell says of the group, "It's slightly over-driven, less polished, lots of Sixties influence: The Kinks, Led Zeppelin, The Animals. It's something I probably should have done a long time ago, but I didn't 'cause I was wrapped up in the Heartbreakers." They released a single, "Feelin' High", in 2010. Jason Sinay left the band in 2022 to focus on his solo career. His replacement is Texas guitarist Chris Holt, who has played with Don Henley and Max Weinberg.
