So I'm looking for a pedal that will give me a good Plea for Purging/ For Today tone something like the tone in this video.

My current gear is a PRS Tremonti SE with a Peavey Windsor Tube head and a Crate 4x12 cabinet with a Digitech Grunge Pedal. I just cant seem to get a tone that I like from it. If anybody has any suggestions for settings or anything new I can add to get a good tone for metalcore it would be appreciated.
Digitech Hardwire TL-2
Shecter Omen 6 with Seymour Duncan SH-6
Epiphone Les Paul Standard
Fender Frontman 25r (crappy)
Digitech HardWire TL-2 Metal Distortion (Makes the amp sound not shitty)

The problem is probably that your amp is not at all voiced for what you want to play though.
Spin 'round carousel when your horse isn't screwed in.

Ibanez RGA42E
Ibanez S420
LTD H-301
Ibanez RG520
Peavey Predator USA
Douglas Grendel 725
Line 6 Pod HD500X
the Digitech (mentioned above) on a mid-gain setting into your amp (on with your regular high gain) should do the trick. it'll tighten up the low end and give you some more saturation than you're currently getting
