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.
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!
