The EarthQuaker Devices Limited Edition Rainbow Machine is a variation on the famous modulation pedal. The Limited Edition Rainbow Machine, with a new sleek, black finish, creates the iconic sweeps and sparkles already well known from the original model. The Rainbow Machine, a pedal of intense modulating capabilities, delivers intricate, scrambling guitar signals through precise engineering and interface design. The polyphonic pitch-shifting powers of the Rainbow Machine are fined tuned with six knobs and two bypass switches to hone in on precise settings that produce mind-boggling results from the most simple of signals. With controls to dial in on simple delay tones to automatically arpeggiated sweeps, the Rainbow Machine hosts a wide range of modulation, chorus, and delay capabilities in between. The EarthQuaker Devices Rainbow Machine Polyphonic Pitch Modulation is a pedal capable of extensive sonic exploration and all around tonal experimentation.
