Like Nothing Else out There

The Rainbow Machine from EarthQuaker Devices empowers guitarists to defy convention and explore otherworldly sounds that are often very unguitar-like. This polyphonic pitch-shifting modulator pedal creates soundscapes that wash your sound in harmonic movement. And the selectable Magic control takes the pitch-shifting effects into totally new sonic territory. By EarthQuaker Devices' own admission, the Rainbow Machine is for "experimenters, adventurists, and noisemakers." The guitarists at Sweetwater know that the journey is sometimes more important than the destination, and the Rainbow Machine is there to propel your musical adventures.

Where it will take you

The Rainbow Machine polyphonic modulator pedal offers pitch shifting up to a 3rd up and a 4th down. This can be controlled by the onboard pitch knob or an expression pedal. Its 6-knob layout allows for deep control of modulation effects going from mind altering to more standard guitar tones like slapback delay, chorus, and reverb. But when the knobs start creeping up, so does the fun. Undefined percussive bursts, chimy high-frequency artifacts, and stepped pitch bends are all available in the Rainbow Machine.

Turn on the Magic

The footswitchable Magic feature on the Rainbow Machine is at its core a regeneration device. It creates aliasing between the primary and secondary controls for sounds that get way out there. Because of how it works, it's highly interactive with the other knobs on the pedal. Tiny changes in them will bring out whole new worlds of modulated, pitch-bending exploration. And if you want a sound that's easier to fit into a full-band context, just kick off the Magic.

Incredibly Weird!

Not for your average player for sure! However if you enjoy experimenting and adding that 5th element to your solo building or chord progressions this is a "magical" way to take it over the edge. I would recommend an expression pedal for the pitch. Trust me!

Out there in a good way

I can't really describe all the things this pedal does. I can't say any of them are super useful, but they are extra fun, and well, out there. I've got it set right now to sound kinda like an old 78 record of a ukulele orchestra. Step on the Magic stomp, and it becomes an old 78 record of a ukulele orchestra from outer space. It's polyphonic, so you can play chords, and it will track just fine, you can also play anywhere on the neck with no tracking issues. This thing is an ear candy machine in studios around the world. I have to say, players who aren't into pedals, or into making crazy sounds should steer clear, it will be a head scratcher for sure. On the other hand, if you love pedals, and or making sounds, add this one to your collection ASAP.

Strange and wonderful

This is an amazing little pedal. It is a chorus, a delay, and… magic. I don't know what it does, but it does it with all kinds of crazy. So far I've used it on uke, bass, guitar and theremin and it pretty much wrecks everything I put though it. By wreck, I mean makes it into unicorns leaving piles of rainbows everywhere. Watch where you step, you may get some rainbow on your shoe. Stomp on the "magic" button and things get really freaky in a hurry. I'm still trying how to work this into a song, I may just have to let it be the center of a cosmic freak-out or something.

Sweetwater Advice

Caleb Lowrey

As a guitar player and electronic musician, I'm always looking for new ways to manipulate and tweak sounds. The EarthQuaker Devices Rainbow Machine is now my go-to effect when I want my guitars and synths to sound like alien spaceships. The controls are intuitive yet inspiring, and connecting an expression pedal allows me to create a huge variety of psychedelic pitch-shifting effects, without letting go of my instrument.
