The amp is DEFINITELY NOT a one trick pony. Lets say it does everything but modern metal but it can get **** aggressive if you throw a boost in front of it.
The one caveat is that the amp is not a swiss army style amp like a Roaster is. You can 'work' the versatility a bit if you have a fender Strat, a Gibson Les Paul, and a Jackson with EMGs at the same gig but it isn't going to give you 4 completely different tones on tap at any given time. That being said, it has plenty of great tones in it. You can do basically any flavour of Fender cleans right to blues using the Clean 'mode', Marshall cleans to blues, to classic rock in Vintage Lo, and blues, to classic rock, more modern crunch / early metal on Vintage Hi provided you have the right axe / pickups for the job. The problem is that you'll be twisting knobs and flipping buttons to access a number of those tones. The only other real option is to have a boost pedal handy and work that along with your volume knobs on your guitar. If this doesn't give you a massive palette of tones, I don't know what will.
One of the really cool features of this amp is that if you set the volume (gain) approx at noon, you can go from clean right to crunch when using the vintage Lo mode, all by adjusting pick attack. It is REALLY cool!!
If you need uber high gain with great crunch and note separation for modern metal / hard rock, then get a Roadster or a Recto Reborn instead. The Recto Reborn has a stiffer clean channel and handle clean to blues to classic rock, hard rock, modern rock, nu metal, modern metal, etc.
