this will totally wash out everything at a certain point, making the tone more "alive" but duller and less focused,
that's the main problem i have with IR's!
a mic recording will have both, an "alive 3D sound" and great clarity/focus and that's the BIG difference
between an IR and a mic'd cab.
the difference might not be noteworthy in regards of frequency response but there is a little bit more
about this than that...
i've stated this quite a few times but mostly got a bad response, which of course will not keep me away from saying this again and again.
funnily most negative response is in defense of the whole IR capturing thecnology, which honestly seems quite outdated.
btw i see exclusively this from the recording/mixing perspective!
IR's work very well, representing the tone of a mic'd guitar cabinet when noodling around, maybe
even for playing live, but when it comes to MIXING it's real pain in the but to make guitar tracks sit in the mix well. mic'd cab guitar tracks on the contrary mostly fit in the mix without any major adjustments, how come!?
peace
