So I'm absolutely in love with the ballsy thump that Derek St. Holmes is getting in this clip: http://www.youtube.com/watch?v=O3J-XYnZHfU

Go to his solo starting at 2:35 to get a gist of it. I know he was using a Les Paul Jr. through a Marshall stack of some variety, but does anyone have any idea as to how he might have EQed the amp? It also sounds like he's using some sort of mild phaser effect, though I'm not quite sure. I play a Schecter Omen FR Extreme through a Mesa Boogie Single Rectifier, and I have a BOSS ME-50 pedalboard. Any ideas as to how I might at least convincingly imitate his tone?
