The stomp station at Bartock’s feet is relatively straightforward. A Voodoo Lab Pedal Power 2 drives a Boss TU-3 tuner, a custom, rooster-emblazoned boost pedal, multiple MXRs—a Micro Flanger, Dyna Comp, Carbon Copy, and Distortion+—and two Line 6 pedals, the DM4 Distortion Modeler and DL4 Delay Modeler.

Premier Guitar’s Shawn Hammond met with Ann and Nancy Wilson’s guitar tech, Jeff Ousley, lead guitarist Craig Bartock, and bassist Dan Rothchild before Heart’s show at the U.S. Cellular Center in Cedar Rapids, Iowa, on March 21, 2015. Ousley—who’s been maintaining the Wilson sisters’ gear (and making them mean cups of coffee) for more than 20 years—walked us through everything from Ann’s custom Martin acoustics to Nancy’s vintage SG and Tele, while Bartock and Rothchild shared their cool customized instruments.
