EarthQuaker Devices Rainbow Machine V2 Polyphonic Pitch Mesmerizer

Unleash Modern Psychedelic Magic and Ambient Texture

The Guitar Sanctuary is proud to feature the EarthQuaker Devices Rainbow Machine V2 Polyphonic Pitch Mesmerizer. Far more than a mere novelty, the Rainbow Machine is a highly sophisticated, 100% digital pitch-shifting modulator designed for adventurous tone chasers. From lush, vintage-style polyphonic chorusing and shimmering slapback delays to wild, self-oscillating pitch cascades, this pedal serves as a powerhouse of expressive potential on any pedalboard.

The updated V2 edition improves upon EarthQuaker's classic design by incorporating silent, relay-based Flexi-Switch® technology on both the Activate and Magic footswitches. This allows for seamless, momentary latching or standard on/off operation, making it easier than ever to inject sudden bursts of pitch-shifting chaos into your solos or transitions. Combined with an optimized lower-noise signal path and a hotter output signal, the V2 ensures your ambient experiments always retain maximum signal integrity.

Sanctuary Expert Tone Profile: Dreamy, ambient, and wonderfully chaotic. While it can produce extreme pitch-climbing self-oscillation, it excels at providing an organic, wide-stereo chorus effect that adds lush, shimmering dimension to clean rhythm passages.

The Trey Anastasio Connection: From Subtle Lushness to Rocket Launches

Famously championed by Phish guitarist Trey Anastasio, the Rainbow Machine has become a cornerstone of modern jam-band and psychedelic rigs. Trey utilizes the pedal in two distinct ways:

• The Ambient Thickener: By keeping the "Magic" switch disengaged and setting the Pitch control slightly off-center, the pedal creates an ultra-lush, wide, detuned doubling effect that rivals the finest vintage analog choruses.
• The Launchpad: Engaging the secondary "Magic" control creates a cascading feedback loop where the pitch-shifted signal continuously regenerates. This allows you to conjure soaring, polyphonic pitch climbs that ascend into gorgeous self-oscillation before instantly cutting back to your dry signal.
