The UK-based electronic instrument maker known simply as the Sonic Manipulator demonstrates some of his unusual audio devices for the fine people of Earth -

The Claude-a-tron – sort of a throttle-synth that seems surprisingly playable, with “pitch & volume, with oscillator modulation, bass & percussion control”

… and the Rap Rod, a push/pull controlled audio scratching device, which appears to use a handheld cassette playhead with tape samples (though more likely an advance alien technology?)
