Earthquaker Devices Pyramids is a Stereo Flanging Device with five presets, eight flanger modes, tap tempo, tap subdivision, 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.
Exquisite Sound
Built upon the same proprietary DSP architecture as the Avalanche Run, Pyramids delivers a convincing jet-engine roar, authentic through-zero tape-style warble, infinite barber pole sweeps, flexible I/O routing, and the ability to re-trigger the LFO cycle via footswitch opens up a fourth dimension of rhythmic possibilities that’s sure to tickle your third ear.
Classic Mode
Tone control for the modulated signal. Clockwise cuts the low end and allows the high frequencies to pass through. Counterclockwise cuts the high end and allows bass frequencies to pass through.
Through-Zero Mode
Delay time for the unmodulated dry signal. This controls where in the LFO cycle the through-zero point occurs, which is where you’ll hear the most drastic cancellation.
Barber Pole Up and Down Mode
Tone control for the modulated signal. Clockwise from the center is a high pass filter. Counterclockwise from the center is a low pass filter. Tone control for the modulated signal. Clockwise from the center is a high pass filter. Counterclockwise from the center is a low pass filter.
Trigger Up and Down Mode
Sensitivity control for the sweep. This controls how quickly the re-triggering reacts to your pick attack. Sensitivity control for the sweep. This controls how quickly the re-triggering reacts to your pick attack.
Step Mode
Adjusts the glide between steps. Low Modify settings produce sharp, stair-stepped transitions between steps. Higher Modify settings introduce a smoother glissando effect.
Random Mode
Adjusts the glide between steps. Low Modify settings produce sharp, stair-stepped transitions between steps. Higher Modify settings introduce a smoother glissando effect.
Controls
Manual controls the delay time of the modulated signal. Manual can also be controlled via the expression pedal. Rate controls the speed of the LFO as well as the rise time in ‘Trigger Up’ mode and fall time in ‘Trigger Down’ mode. The Rate control has three ranges of operation: Slow, Normal, and Fast. These modes are selected by the Rate and Tap toggle switch. Width controls the frequency range of the LFO sweep. You might also think of it as a depth control for the LFO. Mix controls is the volume control for the modulated signal. The modulated signal gets louder when you turn it clockwise and quieter when you turn it counterclockwise. Activate Footswitch features the Flexi-Switch technology. This relay-based true-bypass switch allows for momentary or latching operation. Feedback regeneration control for the modulated signal. Rate and Tap Toggle Switch ‘Normal’ center position is 1:1. The tempo you tap in is the tempo Pyramids will spit out.
