Sarah:
I've tried a few of the later Guild Bluesbirds (post 1999), own a Dearmond M-75T and M-72. The M-75 looks fairly Bluesbirdish, but doesn't exactly feel that way in the hands. The wide shouldered neck is the most similar part. Not too chunky, just not a shallow C shape. Otherwise they don't feel much alike. The Dearmonds are heavier. A little steeper neck angle I think, meaning the bridge is a little higher.
That beautiful red one with the harp tailpiece would be well worth it, is my guess. It would help if you could try it. My sunburst M-75T was essentially new, barely played. The stock frets were it's downfall. Too high, too square, too soft. I like the guitar enough that I finally got it refretted. Not happy about the cost, but wanted to keep playing it. The harp-tailpiece M75 would of course come with Goldtone humbuckers, which I suspect would sound remarkable in that guitar. The "T" models came with 2k pickups ... look like dynasonics but are not. More on the P-90 side; these 2ks are something different, probably the biggest reason I've stuck with the M-75T.
The M-72 is lighter. At least the one I have, which feels and even sounds chambered. Much as I like those goldtones, they sounded a little plinky in the chambered body. (These are twangy, bright pickups, very clear sounding.) Now it has humbucker size P-90s, which totally work for me.
