The Theremin was invented in 1920 by Russian physicist Lev Sergeiyvich Termin. (Known to his friends as “Hi…what?”) Coincidentally, the engineers at Hiwatt have added a 300 millisecond delay to this electronic Theremin, which allows you to create really cool “sci-fi” music without even touching it. Oh, did I forgot to mention? You never actually touch this strange device – the Hiwatt Echo Theremin is a musical instrument that you play by waving your hand near it.
