Many guesses, all respectable, all wrong.
Now for a couple hints,
The Battery box, the cover for the electronics, the six bolt pattern of the neck, and the angled portion of the neck where it meets the body are the only stock shapes to ID it from.
It was bought on the Ebay for $99 shipped, a good price but not anything fantastic.
Last but not least, it ain't a First Act.
Give it a guess or two more and I will let everybody in on it this evening if nobody gets it.
