I'm sure there is a reason why and maybe someone can enlighten me... I'm just wondering if a lot of people are looking for the amp in the room tone... then why aren't more people profiling with reference mic's? I mean if you profile with a mic that is FR like a reference mic then you'd get the cab in the room sound. The same thing with these guys that are making cab IR's, why not use a reference mic and capture the sine sweep and generate the IR from that?
Am I missing something here? Has this already been tried and didn't work?
