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.

Here's Hart's signal path on his board: Walrus Audio Aetos Power Supply, a Loopmaster A/B box, a TC Electronic Polytune (from A of A/B), a Lehle D Loop (from B of A/B), Loop A from Lehle unit - [Greer Amplification Tar Pit Fuzz - Greer Amplification Peacemaker - Walrus Audio Voyager], Loop B from Lehle unit - Walrus Audio Janus Fuzz/Tremolo], a Boss OC-3 Super Octave, a Puretone Buffer, and a Noble Dual Vacuum Tube Preamp.

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