Just below the Mesa is a Bogner Überschall, which is the other half of Tremonti’s punishing dual-amp assault. A G-Lab SD-1 Smooth Delay is connected through the effects loop and is constantly on. Both amps run through Palmer PDI09 passive DI boxes before hitting the cabs.

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.
