well you have to think of the day and age it was done in. I don't believe they would have something like that back then.
The closest thing to getting a junk/lofi sputtery tone like that would be an octave pedal i think. Maybe it was cranked through a compressor that was cranked through a solid state amp that was cranked.
I just imagine it was something cranked up way more than it should be.
We need some of the old guys from the forum to chime in on this
