Description
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.
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 Voice knob on the six stage side simultaneously controls over 30 different parameters, all working in harmony for an inspiring musical experience.
Not only do you get thick, juicy, phasing with pure vintage vibe, but as you turn the Voice knob clockwise, our groundbreaking new modified all-pass structure expands the time response of the cascading all-pass filters seamlessly and continuously, adding spaciousness and airiness to the sound.
Explore a range of fresh musical tones that are not a mix of phasing and flanging, but actually something entirely new. Turn the Voice knob to the right for luxurious true flanger effects, and continue to the far end of the range for lush vintage chorus sounds. There are inspiring musical sounds at every point along the dial, and so many ways to make a sound that is truly yours.
