Well chances are those bands are using PRS guitars and possibly Crate or another "heavy rock" amplifier. Though I am not familiar with the bands to a great extent, I am fairly good with tones and such. So my advice, get a solid body guitar with humbuckers and either a high output solid state(crate..even though I think they suck, alot of people like them; they have a sort of "new rock" overdrive to them)...then maybe some pedals for switching tones. However alot of solid states come with 4 button switches...so take a look at that.
