The Axe-Fx handles most of the effects, but on the floor JB’s pedalboard holds two Sennheiser G3 wireless units with an A/B box for switching between them for guitar changes. From there the signal hits a PolyTune Mini and an Ibanez WD7 Weeping Demon Wah. Last in line is the DigiTech Drop that allows JB to enter low or alternative tunings without changing axes. A RJM MasterMind MIDI Controller switches the Fractal effects and a T-Rex FuelTank Chameleon supplies the power.

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.
