Just like the subject says, I need help deciding if I want to buy a Mark V or a Roadster, or another type of amp to suit my needs for rock/hardrock/alternative and metal genres. I know the Mark V can do old school stuff like Metallica (MoP and such) but could I get some good modern metal tones out of this amp? I have a Menatone Red Snapper Overdrive (basically a tube screamer with more gain and perserves the bass) so maybe I could get some higher gain out of it with that, but I'd also like to play stuff like Shinedown, Foo Fighters, Bullet for my valentine, Atreyu etc. I don't need to sound exactly like the bands I play, otherwise I'd just get a rec. and only play that. I played a marshall JVM2000 DSL 100w and noticed it sounded pretty bad at low volumes and Id like a amp that can sound decent at low volumes but still push out heavy stuff, and clean. The new Rectifier has a 50/100w variac or whatever and that seems cool, but I really want to hear what you guys think. Could I achieve tones slightly similar to BFMV or Foo Fighters while still being able to turn the gain down and play some santana or some dire straits? Would using EL-34s help or just putting some new 6L6s or preamp tubes with higher gain help? I want to hear all your tips, thanks for reading this wall of text, sorry!
