Earthquaker Devices?Rainbow Machine? Polyphonic Pitch Mesmerizer Guitar Pedal \n \n \nThis one is for experimenters, adventurists, and noisemakers. Totally not for purists and/or tone hounds. There are no ?natural sounds? that come from this box. It takes modern DSP and uses it as a tool of future past to create real-time pitch shifting using digital oscillators. \n \nThe Rainbow Machine has been completely re-imagineered from the pixie dust-covered ground up to be more versatile, twice as loud as the original, with an extended delay time, deeper chorus tones, silent flexi-switch footswitches on both the Activate (1) and Magic (2) functions, and most of all, more Magic. \n \n  \n \n  \n \n
