Dan Auerbach has an amazing voice.. But i am more interested on how he mixes his vocals. I run a home studio with Logic Studio. What effects, Eq, would you use to get the sound you hear in his voice on Black Keys Records

I'm interested in ways of making things sound old, and wondered if there was any particular piece/pieces of gear that have a knack for this. By old, I mean anything that has a characteristic that can be related to music recorded and mastered between the 30's up through the 70s. Not that the 70's sound old but... you know.
