Yup...I tried those when I had my Apollo Twin Duo and they really are fantastic plugins that sound great! Quality stuff! That is the whole problem when you get that platform...well, it's not really a problem because it sounds great, it's just that you want it all!
The EQ's and compressors are amazing. I've honestly just been making myself laugh. 20 years of tone hunting, sitting in a room with great amps....and I'm happy as a clam plugging into an interface and pulling up a plugin. It's not practical live, but for playing at home or even doing some session work....they do the trick for sure.
