i found this out the hard way...sims def. dont simulate how a guitar cab hits a mic...
and it really matters on the player..they have to be on top of their game..
that really separates a good sound from a bad sound...where the sound starts from!
beat detective could tighten up a loose player...i don't think nuendo has it tho..
i have the year and a half of metallica vhs from back in the day...i think thats what its called anyway...i'd suggest getting that and pausing it everytime they switch camera angles in the studio and then studying what you see!!!!
thats a good way to burn time and learn stuff...
scoop the mids...that might get you started..and layer..some tight comp will help...
..you know now that you got me thinking...the sans amp pedal that first came out...hmm..the GT2 pedal is a very good sounding metal pedal..it even emulates cabs...i think it sounds pretty good...but not as good as the real thing..
you can put that in line to really any decent amp and get a good sound...it would save you the cabbage of buying a mesa or marshall head...
but if your gonna use a plugin..your sound is gonna sound very weak and not in your face like i presume you want..
i can't really say you WONT get what your want outta the plugin...but i would abandon that idea...and put a mic in front of a cab.
my two cents!
