I've been wondering lately about the guitar-harmonies that can be heard on some of their concerts. On the intro of Seven Seas of Rhye, both from Knebworth (source: Live Magic) and Budapest (video tape) there is a harmonized guitar-slide upwards (similar to the studio version but a two-part instead of a three-part harmony). The Wembley version, however, doesn't feature this lick. So I wonder whether this is genuine or if it was overdubbed. Can anybody tell from Magic Tour-bootlegs (I sadly don't own any)?
If I had to guess, I'd say the slide is authentic. On the Budapest-video Brian plays a similarly harmonized part towards the end of "In The Lap of the Gods". On the other hand, from the video it looks as if Brian stood quite a distance away from his pedal-board whilst playing the intro of SSOR. So I'm not so sure.
I guess he must have somehow worked his pedal-board to achieve that effect?
So another question I'd like to ask is: What tools did Brian use to emulate guitar-harmonies on stage? On "Keep Yourself Alive" from "Live Killers" he makes use of his delays to achieve a harmonized guitar-solo. But the harmonies on "Lap of the Gods" and "Seven Seas" (Budapest/Knebworth) don't sound as if they were done with delays. It must be a proper harmonizer-effect. I know he used one on "Chinese Torture" (cf. "Guitar Extravagance" from the Brixton show) but I read somewhere that he didn't get this particular tool until after the Magic Tour.
So any help and information concerning the "history" of Brian's harmonizer-pedals would be highly appreciated.
