When recording, the actual Impulse Response will be replacing your cabinet in your signal chain. This is great when recording with digital amplifier software such as TSE Audio’s X50, But you can also use your actual amplifier and pedals as well if you have a cable running from the end of your effects loop into your Soundcard.
(Note that in this case you should have your amplifier plugged into your speaker-cabinet or load through a sort of dummy cab/attenuator, as otherwise the power load from your amplifier might damage your equipment.)
The next thing to do is to get your Impulse Response into your project using an Impulse Loader Plugin. There are many plugins available today, personally I use a free Impulse Loader called NadIR from Ignite Amps.
After that, we go into our recording software, and on our Guitar-track, we choose to load NadIR from our plugins. I will be using a digital amplifier with our impulse response, so I make sure that the impulse loader is the final plugin in the signal chain, after our amplifier.
