Effects

hey have you guys ever listened to Scorpian's Rock you Like a Hurricane, the begining of the song i can tell has some dubbing with guitar two different harmonias parts fixed together. But it also sounds like it the rest of the song. Did they really play two guitars for leads at the same time, or is it just effects. If so, what do i need to create a tone like that. I have Epiphone Les paul special, Marshall micro stack, Crybaby original, rp100, and a pod( but at the moment i don't have it with me, i know they have a preset database.)
