The Keeley Electronics Phaser is a 100% analog signal path pedal, with modern features, like tap tempo.
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.
