I use 3 soundcards:
1. Audigy 2 ZS Notebook for the band
2. IKM Stealth for bass
3. Internal card to send,as you want, a guitar track to the Harmonizer.

I'm finding the tracking of a guitar part to be less then stellar. In hind site I should have gotten a MIDI unit. The only people that should get one of the guitar controlled rigs are those that play acoustic guitar solo and have no other options.
Don't say it Pat
