Mesa amps are absolutely NOT metal-only amps. Of course if you think at Rectos you'll think to NuMetal bands and if you think to Mark's you'll think to Metallica but, with a minimum research, you'll find out that artists of every genere uses Mesa amps. Just think that Bruce "The Boss" Springsteen uses a Mark 2c+ (the main Metallica tone amp), Sting uses a 400+ Bass amp, the guitarists from bands like Black Eyed Peas, Shania Twain, Alanis Morisette, Natalie Imbruglia and so uses Mark's and Rectos. The Mark V is an extremely versatile amp, you can control the tone shaping under every aspect, this makes the amp less immediate-dialing but allows you to obtain that tone you hear in your head. That also depends by what's for you "not-metal-sound", I mean, I've heard pop guitarist using a more saturated tone that what I use in my metal band. Think to Mesa's as extremely reliable amps, very well made, very tweakable and, most of the time, very loud that plays like a charm in every context and situation. My main advice is: try it, play wit it, if you like the basic "substance" of the tone then the rest's only "fine tuning".
