The VCA saturates very nicely. The fact that there's a three-channel mixer on both the audio input and the CV input is fantastic.
The VCA starts saturating well before the clip light turns on, so be aware of that.
Another thing you need to be aware of is that this VCA is ac-coupled, so it will not be good for control voltages. Constant voltages just won't go through.
For audio though, it sounds great.
