GT-1000 modeling beats HX Stomp though for sure. And cabs.
Is this supposed to become comedy gold?
I mean, seriously, as pretty much everybody round these parts will know, I pretty much don't give a damn about authentic tones, but I think it's a fair thing to compare authentic sounds when it comes to the raw quality of whatever amp modeling. And regarding that, the GT has pretty much nothing on offer.
Now, if you are like me, you would rather look at the general sound qualities - but it partially falls short there as well, as in the amps compressing too much, hence at least altering your playing dynamics. You might now think of that as a positive thing, sometimes even I do. But usually I'm not. And unlike with other modelers, you can't dial that compression out. The HX amps however compress less but if you wanted, you could add some compression to them as well, such as by raising Sag or Master.
But then, as you're also mentioning the cabs, I'm by now sure it's sarcasm or so. Because there's not even a comparison.
