I sure hope that lame pop song in the you tube vid on the download page isn't on the record.
Sounds like a muff on Crawl to me too, and it sounds like he's got his dirt in a DI feed ... but you could get the vibe with pretty much any nasty fuzz or distortion. I like his dirty sound on McFearless a lot better ... that one seems like he's maybe running the muff through an open wah.
