Product Description


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.

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.

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.


  • To use with multiple output transformer-balanced isolated pedal-specific power supplies,Pyramids’ may be powered from two outlets combined using a current-doubling cable. DO NOT USE A VOLTAGE-DOUBLING CABLE BECAUSE  THAT WILL SEND 18V TO PYRAMIDS AND FRY IT LIKE AN OVEREASY EGG AT A GREAZY SPOON DINER.

Each and every Pyramids is completely assembled, wired, and tested by total human beans in the Great Sphinx of Akron, Ohio, which, coincidentally, looks exactly like the cover of Iron Maiden’s Powerslave.
