Thanks for all the great feedback guys. Here's the signal chain:
My mic goes direct to the Korg PA900. I have a preset for harmonies that follow each of the keys, so I was set to a third above in G major. That way it does not have to track the guitar. (it just KNOWS) I use the same footswitch as if I was playing the KB.
The guitar is a special beast. It's a Frankenstrat, built from the ground up. The body is a lightweight, basswood deal I got on eBay. The neck is a 12" radius Warmoth, all maple. (curly, or flamed, or some such thing)
The inside has 3 Fender vintage noiseless pickups, and an L.R.Baggs Piezo acoustic bridge. I can blend between the two sounds, output separately, or together.
What you heard was about 90% acoustic bridge pickup, with 10% dark neck pickup blended in. It sounds almost as good as my Taylor 714 when it's plugged it.
I love this guitar because it's LIGHT .... about 5 lbs. (compares to my Parker Flys of yesterday) ... and it sounds Soooooooo sweet.

Thanks again. I love that song, too.
