Long-time listener, first-time caller. I'm always interested in deconstructing Page's tone, and lots of people get into the whole violin bow thing, amp, guitar etc. I am pretty sure I've got the guitar and amp part sorted out, but since effects were in their infancy in 1970, it's tough sometimes to "figure out" which effects pedal to use to emulate certain songs. One example that comes to mind is the theremin-sounding part of the solo in Whole Lotta Love.
I am specifically trying to replicate the tone on Immigrant Song. The part that I can't seem to parse out very well is the first verse, the guitar plays an A to E chord, right where RP sings "We come from the land..." etc. I'm basically taking a WAG that it is reverb and tremolo/vibrato.
Thanks in advance!
