I have a peavey vypyr 75 and it kicks ass in metal. I have a review of it with sound clips just search in this forum it must be there somewhere(or you can go via my profile). And as for guitar ibanez s570b does exactly what you say. Metal and everything in between but it is a little expensive now. The vypyr 30 watt version and the 75 are the same except the 75 also has a usb recording interface built in and ofcourse the 75 is louder. Also there are settings available for almost all major band sounds at Vypyr Settings. The WYSIWYG interface of vypyr works really well.
Guitar: Ibanez S570B
Amplifier: Peavey vypyr 75w
Pedals: Digitech Bad Monkey Overdrive, MI Effects Crunchbox, Blackstar HT-Metal, Boss DD-3, Boss NS-2
