for the solo in hysteria:
just a delay, 2 amps, and a digitech whammy is required:
set up like following:
plug guitar into input of whammy, dry out of whammy goes straight to amp 1, and the wet out goes into a delay with the output of the delay going to amp 2.
set the whammy to +1 oct pitch bend and push the foot treadle toe down.
listen to the album version or a live track to get the right delay time.
when you play you get a slightly delayed repeat thats 1 octave higher.
