I was playing YYZ and was looking to put in some rush presets, any suggestions?

I'm playing though a line 6 spider btw (gross, I know)

Not much that Spider can do. I suppose maybe the metal setting minus a little drive and use a little chorus, but yeah, that's about as best as I can suggest for an amp like that.

I wouldn't use any metal setting for anything off of Moving Pictures. I find that the British stack on my Microcube is very close. It's not a very heavy sound at all. Most of the low end is pounded out by Geddy. I don't know any of the settings on the spider, but Id just look for a mid gain British sounding setting. That should do the trick.
