This is an unusual instrument that is seldom for sale in any venue. The Hohner Guitaret was produced from 1963-1965, an invention of Ernst Zacharias. It has a very distinctive sound, like that of an electric thumb piano. Tiny metal reeds protrude above the casing and can be plucked by the player.
Very hard to find and this one is near mint! Everything is in working order and in tune. Comes with original case and new chord.
Thanks for looking!
