Standard model, length of body 19 1/4" wide, back and top laminated maple, brown shaded, black-white celluloid binding around top, highly polished finish, celluloid guard plate, in cutaway style with electric unit E1.

"The Höfner switch system of our electric unit E1 consists of the following part: 1 potentiometer for volume control and 3 slide switches , which, when very quickly operated by the guitarist while playing, make it possible to create the following different effects: When the first slide switch is being used, the second slide switch attenuates the treble notes and emphasizes the bass notes. With the third slide switch the sound can be reduce to half its volume, which is especially convenient for solo or rhythm playing."
