Wow, I read through this thread and man there is a lot of hate. I will agree with everyone who said that basses need to be capable of moving A LOT of air to produce the same amount of volume as a regular acoustic guitar, that is factual. I think there are plenty of ABGs out there that can at least keep up, the Thunderbird being the one I would turn to first.......if my budget allowed. Sadly it does not.
I recently acquired a Michael Taylor solid top ABG and it seems to be doing the task quite well for my needs. My advice is, whatever you do, get a solid top, DO NOT get a laminated top. I say this based on simple physics. Part of that "need to move a lot of air" comes from the stiffness of said top, and from what I have researched on said interwebs a solid top will move more air than a laminated top based solely on rigidity. So do yourself a favor and get a solid top.
