Used very sparingly and low on the mix, it seems to impart some of that phase thing and/or real short room verb thing (with Feedback knob turned up a bit).
End result is the tone sounds a touch "livelier".
Usually when I do Eventide, it's for 80's stereo hairmetal guitar with like .997 on L and 1.003 on R "dual harmonizer" kinda thing.
Here, I'm not doing that, but using it like how we use the Echoplex preamp - just a dab will do ya.
The effect is stereo (and the original, real unit had stereo outs), but panning the guitar as Ed did to the left channel negates the stereo... mostly. And theoretically helps create that slight "phasey" thing.
We know for a fact that they used an Eventide H910 on the 1st album.
I know Ted or Donn (don't remember which, prolly Donn) said:
Dollars to donuts it was used just a hair... or "dab"a slight 10 millisecond delay added to the dry tone with a Eventide
