With all the features and tone of a standard Etherwave Theremin, this is an instrument with a five-octave pitch range and two antennas that control pitch and volume. However, the Plus model has additional features such as the ability to control a different parameter with each hand, as well as control other analog synthesizers such as a Little Phatty or Voyager for a completely new way to play your synth. With no markers or frets (or even neck!), the Pitch Preview function is particularly helpful in allowing you to hear your note before the audience does. This is an unusual and iconic instrument, associated with a range of electronic and other acts.
