Just remembered, there were once fiddle made, can't remember their name or brand, that had no "body" but instead had an old victrola needle in contact with the bridge, which was then connected to a mica timpan (think "eardrum") which then led to a megaphone that stuck out from under the fiddler's chin. I've never heard one, or seen one in person, but you're right, I bet it would get attention, if not a sweet tone. Might be worth building one to find out.Chet W.
