I'm shopping around for a mini head and I think I want to give the Shuttle 6.2 or 6.0 a try. There are some great deals on the 6.0, but everyone has said that it doesn't have the same beefiness too it. I tried the 6.2 and liked it, so I don't want to short myself by getting a 6.0 and hating it. Is the upgrade in the circuitry of the 6.2 worth the $100-$200 more its going to cost me? I'm playing loud, heavy, down tuned metal; not all the way to Mastodon or The Sword, but headed in that direction. It needs to be able to handle me pounding on the B of my $$ Warwick, which the 6.2 seems to be able to do. HELP!
