The Matrix systems aren't there yet as far as I'm concerned. Lets face it Nolly is a guitar player, his rig sounds like a guitar... **** he even uses a 5150 preset on his axe fx. I think your best best bet is a big, bulky, tubed power amp. I hate to say it, but I've tracked with an axe and a lower watt matrix than the one your referring too, and ended up scratching the tracks. To each their own but I couldn't get the tube qualities I really look for in a power section out of it.
