Built upon the same proprietary DSP architecture as the smash-hit Avalanche Run, Pyramids is a Stereo Flanging Device with five user-definable presets (a first for any EarthQuaker Devices pedal!), eight flanger modes (Classic, Through-Zero, Barber Pole Up, Barber Pole Down, Trigger Up, Trigger Down, Step, Random), tap tempo, tap subdivision via the Rate &Tap mini-toggle, a multifunction Modify control, positive and negative feedback, and a variable Mix control, which is something you don't see on a flanger every day. The Activate footswitch features EarthQuaker Devices' exclusive Flexi-Switch technology, a relay-based true-bypass switching platform which allows for momentary or latching operation, making it easier than ever to engage the effect on individual notes or phrases! The Trigger Up/Down modes allow for Side Chain Flanging, in which an external control source (drum machine, sequencer, CV) may be used to trigger the flanger while you play another instrument!
