Not to be argumentative, but "I FEEL FINE" was done in 1964. "WON'T GET FOOLED AGAIN" was in 1971. Other bands had done some things with Feedback, but it was more by accident than anything else. The Beatles are creditied with the first mainstream use of it and purposely using it as a featured part of the song. And 'm pretty sure that John had leaned his Epiphone electic against the amp. So it was an electric instrument. I could be wrong, but belive this is correct. At that time, they would not have been using an acoustic with an amp.
