"The stage is packed with props, but Purgason’s amps and cabs are cleverly hidden in set carts to prevent damage. His rig is fairly simple: a pair of 4-channel Engl E530 tube preamps and a 6L6-powered Engl 850/100 tube power amp running through a blood-soaked Krank 4x12 cab," states this rig rundown, by Premier Guitar.

According to this rig rundown, by Premier Guitar, Brent Purgason uses a Peterson Stomp Classic Strobe Tuner.

"Purgason keeps his signal chain pretty straightforward, as well. After running through a Sennheiser ew 572 G3 wireless unit, his guitar signal hits a Peterson Stomp Classic strobe tuner (even aliens need to tune), before going into a Stereo Mod version of an ISP Technologies Decimator ProRack G," states Premier Guitar.

"A Dunlop Cry Baby Rack Module DCR2SR wah is next, followed by a Radial Twin-City Active ABY amp switcher," reads this rig rundown on Brent Purgason, by Premier Guitar.

"Each side of the Twin-City goes into one of the Engl preamps, which have a TC Electronic G-Force and MXR M108 10-band EQ in the effects loop. (Purgason uses the 10-band EQs to impart a more “British” sound to his guitar.)" states this rig rundown on Brent Purgason.

"he E530 preamps’ right and left frequency-compensated outputs feed a pair of Livewire DIs that are tapped in the event of a cabinet or power amp failure," states this Premier Guitar article on Brent Purgason.

"Managing all the effects is a well-hidden, barely visible Behringer FCB1010 MIDI foot controller," states Premier Guitar.

"Before the signal hits the cab, it flows through a Radial JDX Reactor Guitar Amp direct box that feeds the house sound system," reads this rig rundown on Brent Purgason.

"Seymour Duncan AHB-2. It's the Metal Blackout pickup. Sidenote, it's with the little jumper thing removed. These things are still super, super hot. Even without that." - Brent Purgason
