I knew a man who played his Fender electric throught a device on the floor and then had a small cable with mini-plugs that attached to a hearing aid. He said it was a Frankenstein put together by his audiologist. My friend controlled the volume and it never was loud enough to hurt the little hearing he had.

PS: "He said it was a Frankenstein put together by his audiologist."

I think this is the most important part of this post.
