Way Back Machine.

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.

Two Effects At Once.

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.

Choose Your 4-Stage Phaser Sweep.

Barber Sweep

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.

Envelope Phaser

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.

Classic Sweep

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.

Six Stage Voice: Groundbreaking New Phaser Algorithm

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.

Adjusts the balance of the dry signal and the phase-shifted signal from mild phasing at min to 100% wet at max.

Strongest phasing effect occurs with knob set at 12 o’clock (50/50 mix).

Adjusts the LFO range of the 6-Stage phaser.

Higher settings result in more dramatic phase and/or time modulations as set by the VOICE knob.

Adjusts the range of LFO for the 4-Stage phaser.

A deeper phasing effect is achieved as the knob is turned clockwise.

Sweeps smoothly from pure phaser voicings on the left to flanger tones past 12 o’clock and chorus tones on the right.

Adjusts the LFO rate of the 4-Stage phaser.

Adjusts the LFO rate of the 6-Stage phaser.

Selects from three settings of regeneration that add color and intensity.

off: smooth response.

mild: enhanced frequency peaks.

strong: prominent frequency peaks.

Controls the shape of the modulation sweep.

classic: traditional rising and falling LFO voicings that change in character as the DEPTH knob is adjusted.

barber: continuously rising or falling LFO. Direction is set via a live edit function.

env: touch sensitive envelope phasing effect with range set by the SPEED knob and sensitivity set by the DEPTH knob.

Independently toggles 4-STAGE phaser on and off.

Independently toggles 6-STAGE phaser on and off.
