How do experts mix Metal guitars?

In defense of kool918091274981734091whatever dude, Vinny was saying he would use a 5150 on one side and a 6505 on the other as if that was using two "similar sounding amps but different" when actually it´s not, it would be exactly the same as using two 5150s, they won´t sound exactly the same as many have said, but it would still be using the same model amp on each side. oh and OP´s a dick
 
Though everyone ripping you a knew rectum hole. I figure I'll just through this out, it's a lot easier to just use two different guitars when doubling then trying to change up the tone of the amp.
