earthquaker devices pyramids: stereo flanging device (limited edition; solar eclipse) price : $299.00

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.

modes:
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.

presets:
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!

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.

power
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!
