Kosko FX Phaser, Classic Vintage Phase

Purple Phaser is an analog phaser with a hypnotic design and distinct vintage character.
This pedal is based on the classic Ross Phaser circuit — the foundation of many legendary tones from the ’70s and ’80s. The Rate knob controls the modulation speed, while the unique Recycle knob (feedback) adjusts how much of the effect signal is fed back into the input — adding depth, resonance, and even filter-like textures at higher settings.

Purple Phaser delivers warm, organic modulation with a rich psychedelic vibe — perfect for funk, psych-rock, stoner, and atmospheric guitar work.
