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.

Built upon the same proprietary DSP architecture as the Avalanche Run™, Pyramids delivers 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: Delivers the “classic” jet-plane liquid-silk flanging sound we all know and love and have come to expect from any reputable flanging device.

Through-Zero: Gives you authentic tape-style flanging without all the calibration, biasing, demagnetizing of heads, and so on that a real tape machine - two of ‘em, actually - requires.

Barber Pole Up: “Barber Pole” flanging refers to an infinitely sweeping upward flange with no beginning, middle, or end.

Barber Pole Down: Barber Pole Down is exactly like Barber Pole Up, except the flanging effect goes downward in pitch, rather than upward.

Trigger Up: Similar to Barber Pole Up mode, except in this mode, your pick attack (or pressing the Tap/Trigger switch) re-triggers the flange from the beginning.

Trigger Down: Trigger Down is exactly the same as Trigger Up, only the flanger sweeps downward.

Step: Step mode tries to restore order to the universe by sweeping up and down in stepped increments, kind of like the sequencer on a synthesizer.

Random: Random mode is like Step mode, except the sweep is randomized without reason or rhyme.



1. Manual: Controls the delay time of the modulated signal. Manual can also be controlled via expression pedal.

2. 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 & Tap toggle switch.

3. Width: Controls the frequency range of the LFO sweep. You might also think of it as a depth control for the LFO.

4. Mix: This 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.

5. Activate Footswitch: The activate switch features our Flexi-Switch™ technology! This relay-based true-bypass switch allows for momentary or latching operation.

6. Feedback: Regeneration control for the modulated signal.

7. Rate & Tap Toggle Switch: “Normal” (center position) is 1:1. The tempo you tap in is the tempo Pyramids will spit out. When set to “Slow” (left position), the tempo you tap is divided for a slower sweep. When set to “Fast” (right position), the tempo you tap is multiplied and delivers a faster sweep.

8. Modify: The behavior of this control depends upon which mode you’re using.

9. Tap / Trigger Footswitch: In Classic, Through-Zero, Barber Pole Up, Barber Pole Down, Step, and Random modes, this footswitch is a tap tempo control. In Trigger Up and Trigger Down modes, this footswitch triggers the effect whenever it is pressed.

10. Presets Rotary Switch: Selects between Live mode and one of five presets. Pyramids comes with our favorites programmed in, but you’re allowed to re-write them if you want. We don’t mind.

11. Mode Rotary Switch: Selects between Pyramids’ eight flanger modes.
