I never fail to be fascinated by the sound of the guitars, but as to the subconscious connection, I've seen lots of analyses over the years. One had the rising pattern in "I can't hide, I can't hide, I can't hide" somehow back-brain signaling climaxing in listeners, especially the younger ones just discovering themselves. Certainly when you see vids of how the girls reacted -- frantically jumping up and down and the like -- you might think there's something to it. I don't have enough of background in psychology know whether there's something to that or whether it's just BS. I do remember reading a magazine interview with Jan Berry (Jan & Dean) from late 1964 where he said something like 'yes, there is absolutely a psycho-sexual release associated with rock records with heavy beats." What I will say, and it's something I've repeated often when the topic turns to IWTHYH is the interviews I read with people who were teen who heard it in late 1963 / early 1964 -- it absolutely was a turning point. Most said what you'd expect -- "fresh", "exciting", "sounded like nothing else at the time", but the comment that always stuck with me was from one woman who said "it sounded like the future." Far be it for me to understand a lot the mimed appearances from the era. I guess what guitars were used didn't make much difference to anyone as long as there were guitars. I've seen mimed vids where a full drum set on the recording being played was reduced to the drummer standing behind a single snare which the drummer embarrassingly tapped for the mime performance. And scores of electric leads pretend played on acoustics.
