Eddie Kramer was very happy with Neumann tube mics like the U47
and U67. And on occasion ( like with Jimi Hendrix) he used a Beyer M 160. He also loved the SM58
-mostly for live stuff (like Woodstock) - but I'm sure he used it for some things with Led Zep. On some stuff Robert Plant used his harmonica bullet mic for vocals.
BTW Kramer was Led Zeps engineer for a while in the early days. You got to know where to look....
