KosmosMulti Phaser
Kosmos is a phaser built for endless motion. Choose 2 to 8 stages to reach nearly every classic phaser sound and plenty of new ones, sync the sweep to tempo, and tap in new rhythms live without changing your tone. A full 0 to 100% mix lets you add a hint or go all the way.
Pot 5 · No. of poles
From vintage to deep space
More poles means more notches sweeping through your sound. Step through them to see a light, vintage swirl turn into deep, complex motion.
Select
Two poles: one gentle notch. Light, airy and vintage.

Kosmos is one of seven dynamic effects from Keystone Musical Instruments, an American company based in Bensalem, PA. Every Keystone pedal shares the same small enclosure, MIDI control, APEX expression and free firmware updates, so they work together on one board. Its LED glows teal, its signature color.
