Strymon Zelzah Multidimension Phaser Effects Pedal

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.

Features

Two In One

Zelzah gives you two fully independent, versatile phasers at the touch of a button. Use one at a time, or use both in one of several possible routing configurations. With each phaser having a wide range of control over its tonal characteristics, the possibilities are near infinite with Zelzah.

Meticulously Tuned

Our team spent months working to perfect each aspect of Zelzah’s sound design, making it so that any combination of settings would yield musically useful tones. Experiment to your heart’s content knowing that organic, lush modulation awaits at every setting.

Multidimensional Modulation

Zelzah contains modulation multitudes waiting to be discovered. Our groundbreaking 6-Stage phaser algorithm can take you from vibey vintage phasing to full-on flanging with the turn of a knob. Go even further and achieve iconic chorus tones, all with just one pedal.

Zelzah’s 4-Stage side is just as versatile, with everything from classic phasing to warbly vibrato available, and even tones that border harmonic tremolo territory.

Stereo Flexibility.

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.

Expanded Control.

If you need more presets, connect a MultiSwitch Plus for three presets available at the press of a footswitch. With full MIDI implementation, you can also control just about every switch, knob, and setting remotely with by sending MIDI commands from your controller or DAW via Zelzah’s EXP/MIDI jack or USB-C connection.
