This 2015 Martin D-18 Authentic 1939 is the guitar that Isbell probably plays the most during a typical set. When Isbell gets a new guitar he has a specific method of getting them to open up: He sets them in front of a stereo speaker and blasts Outkast. He strings up this guitar with Martin SP medium-gauge strings (.013–.056).





























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













Zach loves his Sovtek Mig 60 head, which he plays through a cab he built himself at a pipe-organ shop in Denver. Every glue joint is lined with thin leather for maximum air tightness, and it’s stocked with Celestion G12M Greenback speakers.
