I actually suggested for Shane to give Nebula a shot, but he seemed to feel that the impulses were doing an adequate enough job of recreating the amp tone.
I've got Nebula3/NAT3 and I haven't had as much of a chance to play with it as I would have liked. I agree with everyone that it seems that the future may lie with this technology, but I have yet to find time to give it a test run and see if the tone quality lives up to the impressive science.
Current "flat IR" technology is widespread and has given Recabinet an audience that will experience equal quality across a wide variety of platforms ranging from free to expensive, including hardware such as the AxeFX. Conversely, I'm unaware of anyone else who supports the "nonlinear" type of IRs that Acustica is innovating with their platform.
With Recabinet, the concept of speaker impulse response technology is being introduced to a lot of guitarists previously unfamiliar with the technique. Any guitarist can use Recabinet IRs as long as they have a guitar and some kind of audio interface or decent soundcard on their machine. It's a pretty broad market that way.
Conversely, even us hardcore production geeks here have been cautiously optimistic about Nebula3 to the extent that almost none of us have pulled the trigger on actually purchasing it. Meanwhile I have a business to run, so it doesn't make a whole lot of sense for me to invest a ton of time and R&D into a platform with much smaller market share and higher cost to entry.
That being said, since I'm
not purely commercially motivated as a person, I will be doing some impulses with NAT3 as soon as time permits, and they will be available free, as a gift to everyone here. You guys have been very supportive of my ventures, and I sincerely appreciate your votes of confidence as I enter the music products space.
