Reminds me of my old VFE Triumvirate. It's a good idea but I never felt there was sufficient separation between each band of distortion. That was quite a while ago so perhaps the technology has moved on.
But, as you say, it all comes down to the flavour of distortion and if it's to your liking. The demo on the Zorg demo doesn't sound good to me but if you're recording with a Dano Longhorn with dead strings there's only so much tone you're going to get!
