EarthQuaker Devices Pyramids Stereo FlangingBuilt 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, 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 dont see on a flanger every day.
