Here is a regular acoustic hummel with six double courses, that I built about 15 years ago.


Because the hummel is fretted diatonically, that is, it does not have the half notes, it can only be played in one major and one minor key without retuning, so I designed one with a removable fingerboard. By keeping several clip-on fingerboards handy, with the frets in different modes, you can switch keys.
Here is an electric hummel with a removable fingerboard, that I built about 25 years ago.

And here is the same instrument with the fingerboard removed.

In this condition the instrument can be played as a lap steel, and, indeed, IS a lap steel.
I shall insert a soundclip shortly of this instrument played as a lap steel.
There is a long tradition of the hummel being played with a bar. They call it a "noter".
