TGP inspired: how do you like modelers for live use?

[hubberjub***]

I use modelers for demos all the time. They're just so easy to use if you're just throwing down some ideas. I would never consider using one live. I bet they're great if you play in a cover band and need a lot of different tones but I really only use a few. Plus having an amp on stage gives me something to set my beer on.

You gotta move some air, even if you're lining out to a SS amph just to have noise.

I love modellers, but I can't imagine playing where all you can hear are the drums behind you, and a little, compressed guitar tone in my ears. Do you think running a Tech 21 powered extension cab would do the trick?
