Earthquaker Pyramids

A modern flanger inspired by the great classics... and much further

The flanger was born from "old-school" tape tricks, where a copy of the signal was slightly slowed down to create those cancellations and that recognizable movement. Pyramids takes this founding idea and projects it into a resolutely modern approach: from a massive "jet engine" flanger to a very authentic through-zero, including continuous "barber pole" sweeps that give the impression of infinite movement.

Built on the brand's proprietary DSP architecture (the same philosophy as the Avalanche Run), Pyramids is not just a simple flanger: it is a true modulation instrument, designed to move from subtle textures to experimental soundscapes without losing control in real situations.

Who it's for, and in which styles Pyramids makes a difference

Pyramids is aimed both at guitarists looking for a versatile flanger to enrich a clean or crunch tone, and at texture-oriented musicians (post-rock, ambient, electro, noise, prog) who want to transform modulation into a full rhythmic and harmonic element. Thanks to stereo, it naturally finds its place on a "wet/dry" pedalboard, in an effects loop, or directly in stereo input on an audio interface.

In live settings, presets and tap tempo simplify life: you recall a sound locked to the song's tempo and stay focused on playing. In the studio, Step and Random modes provide "sequenced" movements that sit very well on guitars, basses, synths, and even drum machines.
