EarthQuaker Devices has just unveiled Pyramids, a monster of a stereo flanger that lets you dial in sounds from the regular ‘jet plane whoosh’ to the wackiest tones from your imagination.

Choose from eight flanging modes (Classic, Through-zero, Barber Pole Up/Down, Trigger Up/Down, Step and Random), and then go wild with the controls. Tweak the flanger’s delay with the “Manual” knob, then mold the LFO to taste with the “Rate” and “Width” knobs. On the “Trigger Up/Down” modes, you can even use a sequencer or drum machine to trigger the flanger on your main instrument. The possibilities are (almost) infinite—but onboard presents let you store up to five of your favorite sounds.

Pyramids also features “Flexi-Switch” technology on its primary activation footswitch. It allows you to switch between latching and momentary operations, simply by holding down on the switch to temporarily activate the unit.
