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.”’

You were right. I edited the self text.
Try looking up the the Dwarfcraft Grazer
I watched a demo vid. That’s a funky box. In fact - I think Bill Frisell uses that in the last ~4m of this - Bill Frisell ~ La La Means I Love You. It’s such a fantastic cover.
