A keyboard instrument, manufactured by the Hohner company. It is essentially an electronically amplified clavichord, analogous to an electric guitar. Its distinctive bright staccato sound has appeared particularly in funk, disco and rock songs.

Various models were produced over the years, most consisting of 60 keys and 60 associated strings, giving a 5-octave range from F0 to E5. Each key uses a small rubber tip to do a 'hammer on' to a guitar-type string when it is pressed, as with a conventional clavichord. The end of each string farthest from the pickups passes through a weave of yarn. When the key is released, the yarn makes the string immediately stop vibrating.
