Solved
Via reddit...
I googled it for you, and I found an old guitar magazine article that says this:
'Its eerie intro consists of Denis’ guitar processed into cut-up staccato blips by a Yamaha SPX90 with its noise gate engaged. “I just went crazy scratching the chords very fast,” he explains. “I was trying to simulate what the keyboard did on Pink Floyd’s album.”'

If you're curious - somebody at reddit gave me a great answer and I put it in the self text.
I certainly will. I'll have questions again.
that makes sense i was gonna say that really theres a lot of ways to cut it up like that but if you were gonna play it through a guitar a harsh (square) tremolo would be how to do it
Ah - another piece of the puzzle I didn't know.
