I thought the GAD JF-30-12 that I tried recently was head and shoulders above the other 12s in the music store. It didn't displace my Westerly-made JF-30-12 (or other Guilds), but it blew away other mid-range Seagulls, Taylors, Martins, etc. Just my opinion... Fantastic value.
I didn't like the looks of the truss rods on that guitar, though. My concern was that these soundhole-based rod ends might get difficult to adjust with age, and they looked kinda cheapo / lightweight to me -- it's just a perception, perhaps, my being used to chunky, brass nuts in the peghead recesses, but I would worry about long-term. Beyond that, I thought the build quality was good. I think I noted a little coarseness in the finish where the fingerboard meets the body, but still very good.
The GADs use a pretty thick lacquer finish. I think this has turned off a few of the traditional nitrocellulose folks around here. Of course, recent Tacoma products had some occasional issues with finish and bindings... It's all a trade off.
