Earthquaker Devices Pyramids - Hand-Built, Premium-Grade Stereo Flanging Device with Five User-Definable Presets

On the back of the success of their wonderful Avalanche Run stereo reverb pedal, Earthquaker Devices have built upon the same proprietary DSP architecture to create their very own man-made mountain range: the Pyramids!

The Most Versatile Flanger Ever Made

Featuring five user-definable presets (a first for an Earthquaker Device), 8 unique Flanger modes, tap tempo, tap subdivision (via the Rate and Tap mini-toggle), a multifunction Modify control, both positive and negative feedback options, and even a variable mix control, all coming together to bring you a rather unique and versatile flanger!

Momentary Activation

With its silent True Bypass "Activate" switch (which utilises Earthquakers fabulous Flexi-Switch technology), the Pyramids can be activated momentarily, allowing you to easily engage the effect for single notes or phrases.

Eight Different Modes

With eight different modes to choose from, the Earthquaker Pyramids is easily one of the more versatile Flanger effects on the market. These modes are as follows:

  • Classic - this mode helps to recreate those classic studio-quality ADT sounds heard on huge numbers of hit records over the years
  • Through-Zero - make use of this mode to achieve intensified, swirling, dramatic phase cancellation and comb-filtering effects in stereo, of the kind that would normally require hours of calibration, biasing, and demagnetising of tape heads!
  • Barber Pole (Up or Down) - recognisable as the infamous Shephard Tone auditory illusion as heard on TV, films and video games (think: endless circular staircase)
  • Trigger (Up or Down) - gives you an infinitely upward or downward sweeping flanger that restarts the cycle with each new pick attack, or by pressing the Tap/Trigger footswitch
  • Step - sweeps your sound up and down in stepped increments rather than smooth curves, which produces a fun rhythmic flange effect that's almost like an arpeggiator in its delivery, or a sequencer on a synth
  • Random - does exactly what it says on the tin: up and down sweeps in random intervals which creates a chaotic flange effect similar to a synth or envelope filter's sample and hold function

Suitable for More than Just Guitar

Built to accommodate any input source, the Earthquaker Pyramids includes stereo inputs and outputs, giving you a whole range of routing options in live and studio settings. In addition to this you can use it for Side Chain Flanging with the Trigger Up/Down mode activated, which allows you to use an external control source (such as drum machine, sequencer, etc.) as a trigger for the flange effect patched into the left input, whilst you play an instrument through the right input and output.
