That is really interesting stuff. Think about how cool that could be if other people with cool amps let you profile their amps.... then it's not even just taking your sounds on the road, but having access to zillions of boutique amps. Wow. It's interesting that it's not nearly as pricey as I had expected ($1800-ish on Sweetwater).
There are some more information in their FAQ. So its a different sampling that the one Nebula offers.
"Initially, we focussed our attention on existing and well-documented techniques, most of which fall under the heading “Dynamic Convolution”. Even though these approaches seemed very promising at first glance, and certainly useful for recreating simple, soft distortion circuits, they were by no means adequate for complex guitar amplifiers with heavy distortion. Reality has shown that no other company has managed to create a profiling amp by these methods so far.
Other well-known modeling methods, such as a distortion devices framed by a pre- and post-equalizer, have been used in modeling amps of the first generation. They deliver reasonable results, but the sound still lacks complexity, depth and feel; furthermore, these methods don’t qualify for an automated profiling procedure."
I been following this on gearslutz and some of the user profiles I've heard have been completely convincing to my ear. The thing comes loaded with about 200 presets and there is an ever growing amount of user profiles. The capturing process seems quite simple, just a test tone and then some refining by playing your guitar. God knows what manner of witchcraft is in those tones to capture hi distortion, pretty genius. I definitely want one when I can get the money together.
