Zelzah Multidimensional Phaser
Vintage Phasing, Even Better Than You Remember.
Our goal was to capture the rich phasing sounds that were introduced in the 1970s that work so beautifully with electric guitar and electric piano.
In addition to providing the best possible version of the vintage phaser sounds we grew up with, we also wanted to expand the sonic possibilities in a way that was unique and unexpected for a phaser.
To do that, we developed an architecture that contains a modified all-pass filter as the basis for the 6-stage phaser.
A phaser is a filtering effect made up of cascading all-pass filters. There are no delay lines. But with our modified all-pass structure, we are able to expand the time response of the all-pass seamlessly and continuously.
On the four stage side, we wanted to provide the classic sounds you expect from a premium four stage phaser, while adding barber sweep and envelope controlled sweep, and a Depth control that is tuned to deliver great phasing sounds even at very shallow settings.
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 to 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 |
