Strymon Zelzah Multidimensional Phaser Guitar Pedal

The Zelzah phaser pedal brings you straight back to the golden age of modulation effects with its authentic vintage tones and remarkable versatility. This innovative pedal houses two distinct phasers in one unit — a 4-stage side offering classic phasing to vibrato sounds, and a 6-stage side providing everything from phasing and flanging to lush chorus effects. You can run each side independently or combine them for unique sonic possibilities, making it potentially the only modulation pedal you’ll need on your pedalboard.

The pedal features three distinct sweep modes that dramatically expand its tonal palette. Classic mode provides the familiar four-stage phaser sweep with a warped triangle LFO that captures that beloved vintage sound. The Barber mode creates a continuously rising or falling effect similar to the visual barber pole, achieved through synchronised four-stage phasers rather than traditional frequency shifters while maintaining the characteristic four-stage tone.

Switch to Env mode and the Zelzah becomes an entirely different beast, responding dynamically to your playing intensity like an envelope filter. This envelope-controlled sweep creates harmonically rich and funky sounds that react to your picking dynamics, opening up a world of expressive possibilities that go well beyond traditional phasing effects.
