Ok, it's pretty specific, but I'll give it a go. Maybe someone on here that's a lot smarter than I (which is all of you) can explain to me exactly what's going on here... cuz I'd love to know.

At 4:33, on the right channel, there's a growl / grind sound that is just fricken amazing to me. What's going on there? Is that the amp cranked up and a speaker ready to blow? I can't tell. Nor can I tell the amp or guitar combo, because Pearl Jam layers their guitars so well. I'd love to be able to get something similar with the Helix. I'm guessing it's through a Les Paul (which I do have). Any help would be appreciated!
