For the longest time I've been using plugins for amp sims, and while they're alright, they sound a bit too digital and I'm not impressed with the latency. I use a Focusrite thunderbolt interface with a low buffer rate and still encounter latency. Moving on to my main question.. I've always been hesitant to drop $3k on amp modelling hardware but now I'm actually considering it. I'm looking for something versatile with low latency that has a good realistic sound. The Axe FX seems to do just that. With all that being said, is it worth the money? Will I be happy with it? I also looked at the route of buying a good head and digital load box, but it would add up to cost around the same and I wouldn't get the advantage of using different amp sounds. You feedback would be greatly appreciated.
