Product Description

Strymon has expanded its acclaimed family of effects pedals with the Zelzah multidimensional phaser. Boasting two independent 4-stage and 6-stage phaser circuits that can be used separately: one at a time or simultaneously in series, parallel or split configurations — the Strymon Zelzah takes you on a spellbinding sonic experience by producing some of the most exquisite, spiralling and luscious modulation sounds we've ever heard — perfectly voiced with plenty of vibe!

A World of Modulation

The 4-stage phaser on the left side of the Zelzah offers 3 sweep modes that capture an array of nostalgic, vintage phaser and vibrato tones. Strymon call their Zelzah a "way back machine" for a reason! The 6-stage phaser algorithm (right side) can seamlessly venture into flanger and chorus territory via its versatile 'Voice' control, accompanied by a thoughtful resonance switch that richly alters the intensity.

Flexible 2-in-1 Design

As the Strymon Zelzah is essentially two different phasers in a single enclosure, you can configure it in a number of ways to maximise your pedalboard's real-estate — becoming the only modulation pedal you may ever need. Dial in a chorus on one side and a barber-pole phaser on the other, or create a soaring flanger with a pulsating tremolo next door. Use the two sides independently, or together to achieve musical nirvana!

Key Features

  • Two independent effects that can be configured and controlled separately and used one at a time or simultaneously in series, parallel, or split configurations.
  • Vintage 4-stage phaser with three phaser sweep modes: classic, barber, and envelope.
  • Groundbreaking new 6-stage phaser algorithm with a continuous range from classic pure 6-stage phasing to flanging and chorus, all with adjustable resonance.
  • True stereo operation means, under the hood, each half of the pedal has two phasers running side by side (two 4-stage and two 6-stage)  or in series, with independently adjustable stereo spread for each.
  • All controls are carefully voiced to produce musically-useful sounds at any setting.
  • Adjustable input level switch to allow for both instrument and line level signals.
  • Selectable buffered or true bypass.
