So, I'm looking to do a bit of a tone overhaul prior to hitting the studio.

I'm 95% happy with my current tone, which essentially is just a raw Schecter Hellraiser C-1 into the lead channel of my 333xl. But what I want is to tighten up that lead channel. I'm thinking an OD pedal would be the way to go but I don't know which one would suit me best. My band plays an odd brand of melodic deathcore, sort of a cross between All Shall Perish, Through The Eyes Of The Dead and Parkway Drive.

Recommendations? Money is no object.
