I'm trying to grasp a concept of an impulse responses and getting a little bit confused. Most commercially available ones are meant to represent a cabinet with some microphones, but not the amp. And this is really what makes me confused: in order to make cabinet to make sound, you obviously need an amp.
On the other hand, I'm pretty sure you can find impulse responses intended to represent the whole chain. For example, in this video Ola makes one.
The concept of "snapshot of the whole chain" makes much more sense to me, because as I wrote above, you need an amp to make cabinet to make sound.
So, can anyone please clarify this to me? Also I'm not quite sure how I am intended to use IR - for example, after all the effect pedals and my preamp?
