I think you're really close. It's a really nice sound; any differences come down personal preference, and I'd be satisfied just the way it is.
If you want to lose some of the low-end boom, play around in the amp sim's EQ page.
Starts at 1:14, if my memory didn't fail me that is, I remember a similar preset lurking somewhere on the forum but I can't find it.
Did anyone find it? or have this?
Wasn't this an Ultra preset? The video on youtube seems to say so.
