Founded by Mike Matthews in 1968, Electro Harmonix have been at the forefront of stompbox effects for over 40 years. Now, for 2009 theyve turned their expertise to making a vocoder and harmony generator in stompbox format. At its heart, the Voice Box has a 256-band vocoder (the more bands, the clearer the diction), which is impressive. In comparison, the microKorg has an eight-band vocoder. The Voice Box also has six harmony/two octave modes for accompanying solo singers.
