The VH2 is much better than the Yamaha original offering, but falls well short of the competition that includes Digitech and TC Helicon. The mic processor sounds good for tone and effects, but the harmonizer cannot keep up with the smoothness and tracking that the TC gives you. There is lots of control over blend and gender etc, and there is no more hic-cup when you step on the footswitch to trigger a harmony. It's best with just a single voice above the lead, triggered from the auto arranger chord section. For more complex control (like I need) you'll need to upgrade. I'm trying out the new Korg PA900 this weekend, and I expect to love the TC harmonizer that's built in - if it's the same (or close) as the one in the PA3x, then I'm sold!
