the "fridge" in the back ground is indeed awesome and most prolly fun to play with!
To get the kinda of "running around delay sound", actually any delay in the market, be it cheap or rack mount one, also can do it. Its a rather basic use of delay to get those in fact.
But what the edge has in that tone, is a slight shimmering effect in the background within the delay tone that make it stand out. And incidentally, one of the reverb setting in line 6 verbzilla, can do that shimmering sound.
So technically, if anyone wanna do those shimmering delay thingy, a budget of below $300sgd(cheap delay and line 6 verbzilla), will be enough to cover it. Heh, the only thing that doesnt cut it is that we cant write any tune with it, without shaking the image of edge and his delay off, no matter how good the music we can come up with.
And interestingly, one of the earliest person heard playing with those kinda dotted 8 delay sound, was back in the early to mid 70s, predating pink floyd run like hell. Anyway, fella's name was Manuel Göttsching and he himself, is prolly a legend, his band and for his solo stuff which went on to be the earliest blueprint for house music.
