It was even crazier than that, it was four Fender Twin Reverbs!

Considering the amount of watts involved in this, it probably qualifies as rocket science haha

JM: Yeah. The tremolo sound from the intro? That was four Fender Twin Reverbs. Myself controlling the speed of two of them and the producer controlling the speed of the other two. So two amps were recorded on one side of the stereo and the other two on the other side. I recorded the part on the tape without the tremolo, and then I sent the part from tape out to four amps, and he controlled two, and I controlled the other two.

And it took a long time because inevitably the tremolo would go out of time with the track because the tremolo doesn't stay in regular clock time. Also we would go out with each other's amps, so we had to keep looking up at each other after every fifteen second bursts and kind of fess up, "Oh yeah, mine kind of went out of time." It took long time, but I'm glad we did it that way because if we had cut and pasted two seconds of audio, it wouldn't have had the same dynamic quality throughout the six minutes of the song, or however long it is.
