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.


Pyramids ships with five example factory presets:

1- Classic
2- Barber Pole Up
3- Trigger Up
4- Step
5- Random

These are intended to get you started and are by no means the be-all-end-all examples of these modes. Please feel free to modify or overwrite these as you’d like!

Inputs & Outputs

To Use Pyramids in Mono

Plug your instrument into the Left Input and use either the Left Output or the Right Output.

To Use Pyramids with a Mono Input and Stereo Output

Plug your instrument into the Left Input and connect both the Left Output and Right Output to the next stereo pedal in your chain, to two inputs of your DAW, or to two amplifiers.

To Use Pyramids with a Stereo Input and Stereo Output

Plug your stereo instrument into the Left Input and Right Input and connect both the Left Output and Right Output to the next stereo pedal in your chain, to two inputs of your DAW, or to two amplifiers. Pyramids is true stereo and will pan across the stereo field.

To Use Pyramids with Two Mono Sources

Plug one instrument into the Left Input and connect the Left Output to the next pedal in your chain, to a DAW input, or to an amplifier. Then, plug another instrument into the Right Input and connect the Right Output to the next pedal in a separate effects chain, to a separate DAW input, or to a separate amplifier. I have no idea why anyone would want to do this, but it’ll work.

Pro Tip

In Trigger Up/Down modes, you may re-trigger the flanger using an external source in what we call Side Chain Flanging. To trigger Pyramids using an external source, plug your primary instrument (the signal on which you want to hear the flanger) into the Right Input and connect Pyramids’ Right Output to your amplifier or DAW. Connect the external trigger source (drum machine, sequencer, or CV) to Pyramids’ Left Input. To hear only the affected primary instrument signal (as modulated by the external trigger source), do not connect the Left Output. Your primary instrument’s signal will pass through Pyramids’ Right Input / Output, but the flanger will react to changes in the external trigger signal instead of your primary instrument. To monitor the trigger source, connect Pyramids’ Left Output to a separate amplifier or DAW input.

Flexi-Switch® Technology

  • This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.
  • For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.
  • For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.
  • Since the switching is relay based, it requires power to pass signal.


This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
