His demo is honestly not the best, tho I do enjoy his music a great deal.
I do agree with him though in thinking this box is the only one you'd ever need. I'm an absolute convert to this thing. I totally had a backup plan for it. I figured if I didn't like it, I'd sell it and buy a roadster.
I've been blown away by this thing, and it sounds great either through my 2:90 and 4x12, or through my headphones direct-line in.
I have all the base guitar stuff covered. Several clean, heavy, and lead sounds. I also have the weird and amazing sounds covered too with all the delay, ringmod, synth, and pitchshifter effects too.
It's like having a stack of very authentic amps (Triple Rec, Triaxis, Mark IIc+, Powerball, Orange, JCM 800, Plexi, etc.) and having the newest Eventide all at the same time.
The only thing it really can't do is a piano sound. Everything else is just great. It's funny too, because just after I quit my last metal band I think I'll ever play in, I wind up getting the holy grail of guitar rigs. That kind of timing sucks!
