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.
A trio of old and new amps fuel Isbell’s backline and each one gives him a distinct flavor. The Magnatone Super Fifty-Nine is a 45-watt beast that’s powered by a pair of EL34 tubes. In order to keep the volume somewhat reasonable, a Dr. Z Z Air Brake is used. Isbell’s primary amp is this Sommatone Roaring 40 and gives the rig a very Vox-style element.
Special thanks to Tech Michael Bethancourt for taking PG through the nuts and bolts.
