I've got an Epiphone Excellente (reissue) kinda like the Epiphone Hummingbird.. except it has a Rosewood body..
Image-wise: The average person goes wow! because of the fancy pickguards and fret inlays.
Sound-wise: It's a bit more grunty and deep because of the rosewood backs and body.. but i think the hummingbird's not as chunky..
Playability: I haven't actually taken my guitar to a luther to get it set up. Just some DIY, and the actions not too bad.=) The neck's quite thick (Gibson/Epiphone styles) so it's a matter of what you're used to.
Thing about epiphones and gibsons these days (so i've heard) is that the quality ain't consistent. So if you've got to make sure you try the one you're going to own?
All the best "hunting down" that hummingbird!
