Why not ask Andy Patridge what he used?
Seriously, I'm sure the pre(s) used on the vocals on that recording was(were) excellent, but it's more about the voice(s) and how you apply effects that gets the particular sound. As long as the pre is reasonably clear and clean, you can get a track that you can work with. No pre can make up for a poor voice, bad mic technique, inept use of effects, bad mixing, or any of the above. If all those things are in place, you can make it happen with nearly any pre (within reason).
