Just this morning I pulled out my Breedlove Atlas (4 string, fretted) to start preparing for an upcoming gig which will include a lot of acoustic, female vocal stuff (songs like Fever, The Look of Love, Blue Bayou). I don't get to play it very often, particulary in a gig setting (rarely enough room on stage for even one bass!), but every time I do play it, whether it is just acoustically--either by myself or along my neighbor's acoustic guitar--or amplified in a larger setting, I am reminded of just how good it actually sounds. I also have a Rob Allen MB-2, and while they can both "sorta, kinda" sound reasonably close to an upright, the Breedlove actually does a better job. (They are both strung with nylon tapewounds.)
I tried a lot of different ABGs before buying it, and while the Tacoma sounds louder unamplified, it is much bigger, and to me, somwhat uncomfortable to play. I much preferred the feel of the Breedlove to it, and also preferred it to the Martins, Kellys, Victor Baileys and El Capitans that I tried. It also didn't hurt that I got it when GC was closing out the ABJ250 model for a ridiculously low price.
I know ABGs get a lot of flack here, but I think they can be a very useful tool--if it fits in with your musical tastes and needs.
