Irons uses a Kemper Profiling Amplifier live, and all of his profiles are Fender Bassman sounds. Irons is used to playing Marshalls, so he’s currently trying a real-amp approach with only boost, clean, and dirty profiles. “The Kempers can do so much more than that, but I’m still adapting to using them, so I’m going for a basic thing right now.”

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.
