EVH recording style!

I used to have some gear Eddie used in my live rig that he used in his setup like the Eventide Harmonizer that he supposedly left on a Chorus setting.

From what I have read and heard in interviews, Eddie has always recorded dry and then added effects later. So I would assume he goes in the board and then out into his Eventide, Lexicon, Roland boxes etc.

So perhaps if he had his mono guitar track with a L and R send out the board into the Left and Right inputs of his Eventide H3000 and then to his Lexicons and Roland Delays etc, he might naturally have added enough unique signal processing delay and tonal variation that he ends up with a naturally good stereo sound instead of a cloned copy when he comes back into the board on new tracks.

You would have to try such an approach to achieve a likeness I would imagine.

That would be my theory.
