It makes everything way easier and gives you a cool interface to look at!
The way I used to use Recabinet was to track a guitar and then duplicate that track and have Voxengo Boogex with different impulses on each track to try to achieve that double mic kind of sound. It was always a hassle to raise the volume of one or the other and get 2 sounds that fit well because I had to go between tracks. Now I can just have the 1 track and do it all inside the interface because there are output controls for each cabinet and the comparison happens much faster.
I also like how
the sound is a little darker with more of a roar and there is some nice fizz on the top. It should sit better in the mix than some of the older Recabinet impulses that I've been using.
