Ok I guess my guitar's fairly loud on it's own, I'm just very anxious about how it would hold up on the street. It's an auditorium body and I put medium strings on it and play with fake nails, so that does a bit to give it a strong natural tone.

I'll heed your words and just go out there with the guitar then. Here's an example of the stuff I play, to give you all an idea of what I'd playing out there. I certainly like the idea of not having to carry an amp around, as my guitar case is already quite heavy. And if people would prefer me 'o naturel', then that is what they shall have! Now to work on the nerves...
