I've not seen the preset you're talkin' about and i've not found it in axechange...where I can find it?Have you seen the presets that Larry Mitchell & Matt ( Fractal ) just put up ?
I'd get the AC-20 preset, it's really, REALLY close to this tone already ( if you've got a Strat ) !
Also, I'm not sure I hear any chorus though .... To me the intro riff is just swamped w/ Reverb ....
Good Luck !
I did not know the riff ..., so I YouTube'd it and learned it real quick .... Larry's AC-20 preset does get it pretty close, maybe you need just a tad more gain either directly from the Amp or maybe a Drive Block .... I slapped some additional reverb and enhancer on it and it was 95% there.
For me, I would go with an AC-20, Reverb of coarse, and a 'Dimension 1' Chorus (after the cab) with a 'Rate' of .500, a 'Mix' of around 30% and a 'Depth' of around 30%.
