The Many Worlds is an eight-stage phaser with eight selectable phase control parameters, six LFOs and two envelope-dependent phase shift modes. Yes, you can get classic, swirly and rich, vibe-esque phaser sounds from the Many Worlds. The fun doesn’t stop there, however; we take you on a multi-versed quest of Many Worlds to uncover some unique otherworldly sounds as well. The Many Worlds features a robust LFO engine with classics like sine and square sharing the same control with reverse sawtooth and two independently controlled and intermodulating sine waves. Lastly, we've added envelope-dependent phase shift–both up and down–letting you control the phase shift with your pick attack, rather than driving it with an LFO. This gives you an autowah-esque manually controlled phase shifting experience.

The idea for Many Worlds began when we were experimenting with different LFO shapes for a phaser project–initially starting with the core of the classic "orange box" phaser but with a number of extra features. This LFO framework eventually led to experiments involving the modulation of one LFO by another. This is where the name Many Worlds comes from—the "Many Worlds" interpretation of quantum mechanics is a theory by Hugh Everette which states that quantum wave function collapse is actually the superposition of quantum states built by the decoherence of independent wave functions. This leads to the theory of parallel universes where quantum measurements have opposite results.


  • FREQ/ATTACK – Controls the frequency of the LFO. When in envelope control, ATTACK controls the low pass filter frequency in the envelope detector algorithm.
  • MIX – Controls the wet/dry mix.
  • DEPTH/FREQ2/SENS – DEPTH controls the amplitude of the LFO. When in Battle mode, FREQ2 controls the frequency of the second LFO. When in Envelope Control modes, SENS controls the input gain into the envelope detection algorithm.
  • FDBK – Controls the internal feedback, turning clockwise creates a drippier, more intense phase.
  • LFO – Selects which LFO waveform is being used.

The Many Worlds runs from 9 to 18 volts using a standard DC center-negative power supply for pedals. Make sure you’re using a supply that provides at least 100mA.

Running the Many Worlds at 9V will sound great, but if you want a bit more output, a dry signal boost and increased headroom, try any voltage you like up to 18V! The Many Worlds does not run on batteries.
