 So for this heavy tone we've opted for the overdrive 1, just because personally I feel like it's got a little bit more bite to it. We've rolled the gain off quite a lot because less is more sometimes, but we've given it a little bit of a boost with a little bit more volume than we would normally, but we've added a little bit more middle and a bit more treble for the heavy tone just because we want it because we can get. Again we love the American styling of the tone, so we've kept the ISF all the way to the left, but we've given it a little bit more presence just to really cut through anything else, like we tend to work our tones around our bass player as much as we can, so he's got a very thick heavy bass tone, so anything that sits on top of that for us works really nicely. Because the start of the song with vultures is just heavy, it's the kind of tone that makes you want to just constantly just riff and heavy riff all day long, that's perfect for heavy rhythm work I think, absolutely perfect.
