The Keeley Electronics Phaser is a 100% analog signal path pedal with modern features like tap tempo.
Perfection to your own tone with the edge control, now you can be in a unique place…from the first most mellow Phasers to the edgiest ones ever thought of.
Swirl with deep rich phasing or rock out to some cutting, aggressive phasing. You can speed it up or slow it down with a brake-like function and tap in a phase rate/tempo.
This is the first OTA 6-stage Analog phaser with tap tempo and Leslie Style Ramp!
The Keeley Phaser boasts a 6-stage analog phasing circuit based on OTA IC’s. Phasers with these circuits are known for very rich and deep phaser sounds. The phasing is not as mechanical as their JFET cousins and this contributes greatly to their lush sound. The Keeley Phaser has a beautiful resonant response in the slow speeds and a sonorous shimmer at the faster settings.
While Keeley were working on the sound, they were also looking for new methods of control. Features like speed ramps and tap tempos were what they had in mind. They have tried creating some of these features without digital help at first. It soon became apparent that this was very limiting.
Keeley wanted the digital circuitry to feel like was an “Invisible Hand” turning the knobs on your completely analog effect. This is very much what they achieved with the Keeley Phaser. Your signal is never sampled, your sound never deconstructed. It’s as if an impossibly good guitar tech adjusted your phaser to the exact speed you were tapping.
In addition to the tap tempo feature Keeley added a ramp that allows you to merge seamlessly between two different speeds. They were looking for something similar to the brake on a Leslie. This feature turned out to be way more fun than expected!
