What kind of guitar effects does Alex use in Grace Under Pressure? Specifically in Distant Early Warning and Red Sector A? I can't think of anything that he uses and I even play it with no effects which(obviously) doesn't sound like it. I guess this oughta be the place to post this question? I'm not sure...

Distant Early Warning is a chorus with long reverb/delay. The early reflections retain the high frequencies. You can almost simulate this with a compressor, but mostly the sustain comes from the reverb effect. Alex uses the same type effect all over Power Windows.

Red Sector A is a chorus with a stereo ping-pong delay set fairly long. If I remeber around 330 to 340ms, but with only a couple of repeats.
The solo is the same effects with a harmonizer set to a perfect fifth above.
