good vibrato, may be a pedal involved as well, not sure, I can get very close with a high gain amp setting and vibrato
Just a lot of gain and a Phase 90.

If you're talking about the swell he hits, after he does the appergio, he uses an MXR Flanger, MXR Phaser, and some gain. Slightly bend the note initially and vibrato it at the end. Play around with it until you get it to sound close. Getting Eddie's sound is a thorough pain in the ass.
