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.

Jimbo Hart's main ride is a 1970 Fender Precision Bass strung with Ernie Ball Flatwound strings (.045-.105). He's had it for over 7 years and he recorded Jason's last record Something More Than Free almost exclusively with this 4-string.

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