The 1980s & 1990s was the time of cassette players being introduced with musical toys, such as the animatronic children’s toy ‘Teddy Ruxpin,’ whose mouth and eyes moved while reenacting stories.  Next was ‘Talkboy,’ a tape Recorder/Player that could change your voice, as seen in the 1992 comedy film, ‘Home Alone II.’   It spawned the production line of electronic sound novelty toys to include the Talkboy F/X Drummer Electronic “Air Drum Pen.”  The Nasta ‘Hit Stix,’ another air instrument, was also a big hit that didn’t actually hit anything.  Kids could play “air drum” as inside the tip of each drumstick was an inertial switch that triggered the snare drum sound circuit when the stick was hit or shaken.
Kawaski’s ‘Keytar’ and Radio Shack’s ‘Electronic Guitar’ promised endless hours of jamming as a ‘one-man-band’ on a guitar shaped instrument with keyboards and buttons for special effects, chords, and rhythms.  Unlike its real-world counterpart with magnetic pickups, these toy guitars had their own speaker mounted directly on top, producing ‘hot’ sounds and endless feedback.
