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.

Isbell saw this Castle Creek Dobrato Respohonic at Corner Music in Nashville and bought it immediately because he thought it was the “stupidest idea in the world.” But once he got it home he quickly realized how great it is.

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