Howdy, welcome to the board!
Sorry, I have no Gibson acoustic, lots of electrics though.. If you have access to a guitar/music shop, stop and take a look at the Yamahas. The FS series is a smaller, great sounding, concert sized acoustic. I have the FS820, solid Sitka spruce top with Mahogany back and sides. The FS830 is same build, but comes with Rosewwod back and sides and a little bit more bling. They run $249 and $299 respectively. These little dynamos pack a lot punch for $$. The Martin 00 and 0 sizes are smaller yet and one of those may be perfect.
Good luck on finding "the one" ! 🙂
