Willie-O...Regarding the B25 Gibson, that's exactly what I was thinking as I read down the thread! I regret dealing mine (or regret needing the Kraft Dinner or whatever I sold it for at the time). Since then I've had a small body mahogany and spruce guitar made by Josh House (www.houseguitars.com) which has similar characteristics, intentionally, though maybe not quite as much thump without "bluegrass" strings.
"Woodiness" can be a function of strings, nut, saddle, pins, even set-up on certain guitars, so it pays to experiment.
I agree with Guest too, Ted Thompson guitars have it, and I've played a few which excelled in every other way too.
