Guys, just encountered a problem - if I change different mic's on any cab - nothing really changes, sound is the same. I've run through spectrometer all of the mic's and find that my ears not playing tricks on me - nothing really changes at all (and suprise is twise - the curve  is too flat to sound like an real cab impulse).

Is that some sort of glitch or I had missed something?

P.S. When I bought it like 7 mouth ago - everything worked fine (mic change - sound changes, spectro - curve naturaly behaves as it's real impulse). Latest firmware updates installed.
