The cool thing Page did, or their producer, was get all kinds of different vibes on all those songs.
Most Zep recordings were produced by Page, BTW.
Page has stated that, as producer, he deliberately changed the audio engineers on Led Zeppelin albums, from Glyn Johns for the first album, to Eddie Kramer for Led Zeppelin II, to Andy Johns for Led Zeppelin III and later albums. He explained that "I consciously kept changing engineers because I didn't want people to think that they were responsible for our sound. I wanted people to know it was me."
