A.P. asked me about the Theremin recently, and apparently there is a device made by Hiwatt, sold at Amazon, that simulates the sound of the Theremin.
The Theremin was invented in 1920 by a Russian physicist named Lev Sergeiyvich Termin (his name was later changed to Leon Theremin). It's a unique instrument because the Theremin is played without being touched! As your hand approaches the antenna, the pitch gets higher. The Hiwatt engineers decided to add a new dimension of sound to the Theremin by adding delay to the unit. The Hiwatt Theremin has 300 milliseconds of delay that adds more depth and greater ability to create sci-fi sounds
This isn't an actual Theremin, but a guitar effect pedal, sold at various guitar stores, such as MusiciansFriend, and elsewhere.
