In Version 2, the Rainbow Machine has been completely re-imagined 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 flexiswitch footswitches on both the Activate and Magic functions! EarthQuaker Devices designed this pedal with sounds you simply can’t get anywhere else, going from dark vintage to outright whacky sparkle!
The Pitch control adjusts the frequency of the polyphonic pitch-warped harmony from a fourth below your input, to a third above, and every atonal pitch in-between. Noon is the unison position. Use the Primary function control to adjust the volume of the polyphonic harmony.
You may add in an accompanying octave or thicken the modulation by bringing up the Secondary function control. The Tracking control adjusts the lag time between the wet and dry signals, and the Tone control rolls off some treble for a darker, “vintage” sound. Clockwise is bright, counterclockwise is dark.
Pro Tip: The Rainbow Machine’s pitch warping behavior is entirely dependent upon the Pitch knob’s position relative to noon. Set above noon, echoes, pixie trails, and other effects will ascend in pitch as they sustain. With the Pitch control below noon, any lingering effects will descend in pitch. This becomes extremely important when using the Magic function.
The Secondary control adds an octave of the Primary harmony. When the Pitch control is above noon, Secondary adds an octave above the harmony. When the Pitch control is below noon, the Secondary control will add one octave below the harmony. With the Pitch set to noon, the Secondary control adds an additional chorus voice for modulated, triple-tracked tones. Use this control to blend in faux-shimmer sounds or a low-frequency rumble. It’s up to you. From there, it’s only a matter of how weird you wanna get.
And you can choose how weird you wanna get with the Magic control. This is a regeneration control that creates aliasing (among other things) by feeding the Primary and Secondary signals back on themselves and each other, and a bunch of other stuff no one understands.
With the Magic engaged and the control set low, you can squeeze a few extra repeats out of whatever setting you happen to be using. As you increase the Magic control, you’ll start noticing increased ambience, resonant, edge-of-oscillation pitch-shifting delays, chorus, metallic digi-flanging, ascending (or descending) pixie trails, controllable self-oscillation, squalls of synthetic noise, whale song, and finally, distortion. It’ll take you way beyond and open up your third eye, trust us. In conjunction with the Tracking control, the Magic creates wild pitch take offs and descends, chaos chorusing, shrieks, groans, gurgles, briggles, bruggles, bridals, wizard-blessed wizardry, signal transformation, imminent destruction, and other general mayhem.
Maybe you only wanna get weird for a second? Okay, with the Rainbow Machine engaged, hold down the Magic footswitch, get weird, and then let go to return to your boring old Magic-less guitar tone. Or, press the switch like normal, and the Magic remains engaged until you press the switch again. Ditto for the Activate switch. Press and hold to use the Rainbow Machine as a momentary effect, then let go to bypass; or feel free to press the switch like normal and use the Rainbow Machine like you would any other effects pedal.
Each and every Rainbow Machine is harvested by hand in the (pixie) dusty Rainbonium mines of sunshiny Akron, Ohio, USA.
Controls
- Pitch: This controls the pitch of the harmony. All the way counterclockwise is a fourth down; all the way clockwise is a third up. The middle position is unison. The pitch can be controlled by an expression pedal as well.
- [Pro Tip: With the Pitch control set to noon, the Rainbow Machine acts as a chorus. Use the Primary control to adjust the wet signal volume, and select the delay time with the Tracking control. The Rainbow Machine’s tracking improves as this control is increased, so turn it up (clockwise) for tighter tracking with a shorter delay time, or turn it down (counterclockwise) for longer delays and more ambience.]
- Exp Jack: This is an expression pedal control jack for the pitch. The Pitch control is defeated when an expression pedal is inserted. EarthQuaker recommends the Moog EP-2 or EP-3 for use with the Rainbow Machine and cannot guarantee that any others will work.
- Primary: This controls the volume of the Primary pitch-shifted signal. Unity gain is at about noon. Anything above will boost the signal.
- Secondary: This controls the volume of the secondary pitch-shifted signal. Unity gain is at about noon. Anything above will boost the signal. The Secondary controls the octave up/down from the primary pitch. With the Pitch knob turned counterclockwise from noon, the Secondary yields an octave below the Primary, whereas turning clockwise yields an octave above. With the Pitch set to the noon position the Secondary thickens the Primary effect creating an ‘tri-chorus’ type effect and you can adjust the tracking to make it more (or less) prominent.
- Tracking: This controls the amount of lag time between the direct dry signal and the warped wet signal. The pitch-shifted signal will track right on the dry signal when this control is all the way clockwise. It will start to lag behind the more it is reduced. This function is especially useful when the Magic is engaged.
- Magic: This adjusts the “weirdness” of the effect. The end result is a wide variety of wild effects depending on where the other controls are set. The Magic control will only work if the Magic switch is engaged and the Primary and/or Secondary are in use. (Technically, it’s a regeneration control that creates aliasing between a mix of the primary and secondary functions feeding back against each other.) This control will go into self-oscillation and distortion at the full-clockwise position.
- Tone: All the way clockwise is full signal, turn counterclockwise to soften the highs.
