Strymon Zelzah Multidimensional Phaser

Step on Zelzah, play one chord, and you’re instantly taken back to a world of classic phaser tones as they were always meant to sound, perfectly voiced, with tons of vibe. Vintage 4-stage and 6-stage phasing with controls that allow seamless transitions to vibrato, gorgeous flanging and chorus, and new sounds never heard before—all instantly musical with great tone all the way across every dial.

Zelzah is actually two different phasers, side by side in one pedal. Zelzah’s 4-stage side gives you a wide array of classic tones ranging from phasing to vibrato and more, while the 6-stage side provides phasing, flanging, chorus, and all points in between. Dial in a chorus on one side and barber pole phaser on other, or a phaser on one side and tremolo on the other. Use the two sides independently or together in a variety of configurations. Zelzah may become the only modulation pedal you keep on your board.

The first Sweep mode is labelled “Classic” because this is the classic four stage phaser sweep we all know. In this Sweep mode, a single LFO with a warped triangle shape creates that familiar vintage sound.

Similar to the visual effect of a barber pole, the Barber sweep is a continuously rising or falling effect that is traditionally done with frequency shifters. In Zelzah we have used an arrangement of synchronised four stage phasers to produce the effect while maintaining the four stage sound.

Set the Sweep switch to Env and you’ve got a whole new pedal under your feet. Now the phaser responds to your picking like an envelope filter/auto-wah would, with the phaser sweep being dynamically controlled by your input signal, creating harmonically complex and very funky sounds.
