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