Electro-Harmonix Iron Lung Vocoder Built around the finest aspects of our praised V256 vocoder, the Iron Lung is the baby brother housed in our smallest, die-cast chassis . The Iron Lung uses the highest resolution of 256 bands to deliver defined vocoder performance while our famous Gender Bender control lets you adjust a male to female emphasis that delivers numerous and exacting possibilities at the turn of a knob. An XLR input allows your microphone of choice to be used with 3 independent gain controls. To round it out, the tone control integrates with the Gender Bender to refine the tone to exactly where you want it to be. Use a guitar or keyboard for polyphonic delivery. One of the very classic instruments from the past made available to every musician at a classic price!
