The Electro-Harmonix Iron Lung Vocoder is a vocoder effect pedal from Electro-Harmonix, processing guitar signal through a microphone input to produce vocoder speech synthesis and robotic voice effects. The vocoder circuit analyzes the microphone input and applies its spectral shape to the guitar carrier signal, producing the classic robot voice and vocoder character. Controls include Sensitivity, Dry/Wet blend, and Mic input level.
