Strymon Zelzah Multidimensional Phaser, Midnight (Limited Edition)

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 labeled “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 synchronized 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.

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.

Zelzah features full stereo in and out capabilities. It can also receive mono input and still give you stereo output if you’d like to use it as the stereo origin point of your signal path. When using stereo outs, use the Stereo Spread live edit function to increase the stereo spread between your outputs to create a dimensional stereo image with life and movement.

Being true stereo, Zelzah processes incoming stereo signals independently, with the left input being treated to its own 4-Stage and 6-Stage phasers, and the right input also having its own respective phasers. Pair that with the ability to also process incoming stereo signals in Split mode, where the 4-Stage phaser processes the left input only and the right input is processed by the 6-Stage phaser, and Zelzah just may be the most flexible modulation pedal on your board.
