Rig Rundown: Jason Isbell & The 400 Unit

“Cooder-casters,” boutique amps, classic Gibsons, and a healthy amount of pedals give fire to Isbell’s brand of Southern-bred rock.

While not his #1, this might be Hart's favorite bass—a 1963 Fender Precision Bass strung with Ernie Ball Flatwound strings (.045-.105). The reason it means so much to him is because this is the bass he practiced and marched with during his time participating in his high school's marching band. His hometown musical director recently sold it to him.

Special thanks to Tech Michael Bethancourt for taking PG through the nuts and bolts.

Steve Carr’s first amp build was a Fender Champ clone. It didn’t work on the first try. Luckily, that didn’t stop him.

The North Carolina amp builder is famous for his circuit-blending soundboxes, like the Rambler, Sportsman, and Telstar. Here, he tells us how he got started and what keeps him pushing forward.

Steve Carr started building amps because he loved playing guitar. He and his friends cobbled together a band in Michigan City, Indiana, in high school in the mid-’70s, and the gear they played with seemed like a black box. In the pre-internet days, getting information on amp voicings and pickup magnets was difficult. Carr was fascinated, and always wanted to know what made things tick.

John Mayall in the late ’80s, in a promo shot for his Island Records years. During his carreer, he also recorded for the Decca (with the early Bluesbreakers lineups), Polydor, ABC, DJM, Silvertone, Eagle, and Forty Below labels.

He was dubbed “the father of British blues,” but Mayall’s influence was worldwide, and he nurtured some of the finest guitarists in the genre, including Eric Clapton, Peter Green, Mick Taylor, Harvey Mandel, Coco Montoya, and Walter Trout. Mayall died at his California home on Monday, at age 90.

John Mayall’s career spanned nearly 70 years, but it only took his first four albums to cement his legendary status. With his initial releases with his band the Bluesbreakers—1966’s Blues Breakers with Eric Clapton; ’67’s A Hard Road, with Peter Green on guitar; plus the same year’s Crusade, which showcased Mick Taylor—and his solo debut The Blues Alone, also from 1967, Mayall introduced an international audience of young white fans to the decidedly Black and decidedly American genre called blues. In the subsequent decades, he maintained an active touring and recording schedule until March 26, 2022, when he played his last gig at age 87. It was reported that he died peacefully, on Monday, in his California home, at 90.
