Hi Dave, just listened to a few of your tunes & although you'd get decent results with FG-X it's better suited for louder rock, R & B & metal. It doesn't play nice with soft/ quieter material.
I'd try the demo but I think you'd be better off with a more transparent limiter like FabFilter's Pro-L or the new Flux Elixir limiter.
By the way the VCC is a channel console emu, placed on channels & used more with mixing tracks in mind. It's not mastering software like FG-X although I use it in my mastering chain with great results.
