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! • True-Stereo flanging Device built upon the same groundbreaking proprietary DSP architecture as the massively popular Avalanche Run • Five user-definable presets, a first for any EarthQuaker Devices pedal! • Tap tempo • Tap tempo subdivision via the Rate & Tap mini-toggle • Multifunction Modify control • Variable Mix control; a rarity on a flanger pedal • Positive and Negative feedback • Eight flanger modes • Expression control over Manual control available in all modes • Side Chain Flanging allows the effect to be triggered by an external control source in Trigger Up and Trigger Down modes • Stereo inputs and outputs for flexible routing • Activate footswitch features EarthQuaker Devices' exclusive Flexi-Switch technology for latching or momentary operation • True bypass • Silent relay-based switching • All-analog dry signal path • All-digital wet signal path • Includes 9v DC power supply
