EarthQuaker Devices Pyramids

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.

The Pyramids' eight flanger modes are:

• Classic: delivers the “classic” (duh) jet-plane liquid-silk flanging sound we all know and love. In this mode, Pyramids recreates the studio-quality sounds of old-school ADT (automatic double tracking) as heard on timeless recordings by those fabulous mop-tops from England (you know which ones) and on the most ripping double-tracked riffs to come from the New Wave of British Heavy Metal.
• Through-Zero: provides authentic tape-style flanging without all the calibration, biasing, demagnetising of heads, and so on that a real tape machine - two of ‘em, actually - requires. Use Through-Zero Mode to achieve intensified, swirling, dramatic phase cancellation and comb-filtering effects in stereo!
• Barber Pole (Up or Down): infinitely sweeping upward or downward flanging effect with no discernible beginning, middle, or end creating an “endless circular staircase” effect derived from the Shephard Tone auditory illusion popularised in television, video games, and film.
• Trigger (Up or Down): In this mode, Pyramids provides an infinitely upward or downward sweeping flanger that restarts the flange cycle with each new pick attack or by pressing the Tap/Trigger foot-switch.
• Step: sweeps up and down in stepped increments, producing a rhythmic flange effect similar to an arpeggiator and/or sequencer on a synth instrument.
• Random: sweeps up and down in random intervals, creating a chaotic flange effect similar to a synthesizer or envelope filter’s “sample & hold” function.
