The Scorpions and Van Halen one are SPOT ON. Dio one sounds great too. Def Leppard, holy wow you're getting some authentic sounds immediately identifiable. Dream Theater one sounds great. These are your best sounds ever, man. I take it that you had to do these without any "premium" IRs either, right? So big thumbs up on the Amplifire making it's way up to the big boys' territory. This is very gig ready especially for cover bands. I don't remember hearing so many sounds from Line 6, Boss, Eleven Rack, Axe FX, Kemper that made me think "that sounds EXACTLY" like the bands.
