If you're talking about on a recording, you're going to find it hard pressed to get a sound just like you hear. There are just too many things to consider. And just because they endorse Dual Rec's doesn't mean that that is all they used in the studio. There's probably different amps layered together. Then you have to consider the player, the guitar, the pickups, the pick, the technique, the room, the cab, the speaker, the mic, the pre, the compressor, the eq, etc, etc, etc.
To answer you question directly, I have never heard tell of a site that gives settings for certain bands. I think there are a few groups for Triaxis users, but I don't know of any for the Dual Rec.
My recommendation is that you just dial in something that you like. Find a sound you like. If it happens to sound like someone else, so what? It's a sound that you like and that's all that matters. Get in there and start turning knobs. It won't kill you.
