One thing that you're going to have to accept with an ABG......no matter how big the body, you'll need a small practice amp to be heard if playing more than one or two acoustic guitars. There's no way around it. No matter what
anybody tries to tell you about a particular model.
Over the years, I've owned several different brands and models and that is the one thing that's been consistent about all of them!
That being said, an ABG is IMHO, an very important tool to add to the bag of tricks.Here are a couple of other tips I've found out along the way.......
If possible, get a fretless. Every fretted ABG I've owned has had some fret rattle to some degree. Believe it or not, when I first got my Michael Kelly Fretless Dragonfly 4, it had roundwounds on it and, like all the others exhibited fret rattle.
I did some research and reading and decided to install tape wound strings and get a Pro setup. It was worth EVERY penny!
I sounds and plays VERY nice with no more annoying fret rattle.
BTW......my MK has a Jumbo Maple body and, when plugged in, comes very close to the sound of an upright bass with the tapewounds on it
Good luck! Let us know what you decide.
