Jim,

Mine is an acoustic 700 and I have fiddled with all of the knobs.

Not complaining, because it is cool, but no matter what you do or where you set the controls (in my experience) you will always lack that warmth, sustain and resonance of a real acoustic, so I can't see using it up front, because all of my playing is based on really subtle string attacks, holds, bends, harmonics, and moving my hands in different directions from the sound hole.

So again, I think it is wonderful in its place but will always have limitations, because, well it is not a guitar. It is a guitar synth.

Make sense?
