Well, I am a kind of beginner using UA plugins for about one year.
Its really a revamp in my mixes as it supposed to be comparing with the investment made.
VOG really bring power to the mix but I've never used in a final mix because it distorts the final whole thing mainly if you use it in more than one track.
A better investment is to buy a hassle free (hardware independed) Sonnox suite that are really superior. At the end I use more Sonnox than UA.
Please consider my lac of experience but to make my voice and/or bass to sound like God will take a while. :-)
About jailed freedom of plugins jailed to UA hardware bothers me a great deal because I didn't get the plugins for free.
And.. who can handle the pressure for UA demo 3=VOG 1=UA
It's a one trick pony, it's a good trick and it might be useful for you but it's nothing exceptional, would be good value if it were closer to ten dollars.
