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.

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.
