still ... I'm going the outboard route for the following reasons:
1) more harmonies - the VL3 has 4 parts and you can get 8 in choir/double mode
2) allows for looping onstage with no extra gear
3) best guitar effects in town
4) allows for guitar fueled harmonies without switching mics around ... one central processor
5) I want the same effects & harmonies whether I play an acoustic guitar, piano or arranger situation. I want this one little box to be my main mix ... my "go to" setup - the rest is all academic. I can play anything for bass, drums and chords if the vocals and tracks are all in order.

For small, quick jobs - the built-in harmonizer in the PA900 is more than sufficient, but if I'm bringing a guitar - I need more flexibility.

I'll be couped up the nest 3 days tweaking this new setup before I head back to the jersey Shore on Monday for it's stage debut!

Fingers crossed that I don't pull too much more hair out ... can't afford it!
