Top of the neck? A resonator? Do you feel a tug on your leg? I don't see how anything that would "resonate" would be attached to the neck. What do you mean, "top?" -- above the fingerboard, or on the peghead? I've seen a resonated mandolin, that had a wider back than the sides and top, so that you had sound holes around the circumference, and it was a loud little thing, I'll tell you. And resonated guitars, with metal cones instead of wooden tops, but I don't think that's what you're after. Gibson once made a guitar with two sides, one inside the other and a space between, so that it had extra soundholes -- "f" holes -- around the circumference, but it sounded like, well, kaka, if you must know.

I don't know of anyone who's built a resonator like banjos have, but for guitars. I suppose it might work. A dulicmer maker in Galax, VA, used a double bottom as a kind of resonator for that instrument, so it might work.

Hmmm... I've got some maple arched guitar backs/tops (interchangeable in jazz guitars) that might be rigged behind a regular guitar. I'll try an experiment and let you know how it turns out.

Later, folks.
