Besides his PRS guitars, Herring brought this parts S-style guitar built by guitar tech Joel Byron on Widespread’s sojurn to Nashville. It’s “sort of a ’50s style,” says Herring. The guitar’s got a light ash body (from MJT), which he says tends to resonate better, a USA Custom Guitars neck, Don Mare pickups, and a Callaham bridge chosen to give the strings a more modern spacing. As with all his guitars with whammy bars, he uses four springs under the bridge. The axe’s middle setting activates the neck and middle pickup.
