The VBL is a fantastic Vst. I use it to give my tracks colour whenever I feel they lack some character. And most of the times, VBL delivers the colour I want. Guitars, bass, drumbus!!! and even piano benefit from the great variety of tones that come from this baby. I also used in the mastering chain lately, giving my track an edge so it sounded the way I liked it. And that is the purpose of having something in your signalpath isn't it? It has to be there for a reason.
Insert the Vst, go happy with the input level, the amp level, dial in some brilliance, focus the effect on just the higher frequencies, dial in whatever you want. You will likeley discover a colour that you like.
