Reverse guitar (from Fri, 30 Jan 2009) and a lot of plate reverb.
Also some samples and effects.
As an aside, does anyone else remember the expression "faceless techno bollocks"?
It was used in the music press during the "britpop" era to both describe and deride the fact that electronic music acts didn't have the kind of easily identifiable charismatic frontmen , unlike say, Menswear or Bon Jovi.
As such it was immediately picked up an used by a badge or pride by fans - t-shirts were printed, if I recall correctly.
