Bringing together beautifully simple design of rate and depth knobs with a switch for toggling between nuanced two and four stage phasing stages reminiscent of coveted vintage sheen, the Keeley Phase 24 Phaser marries classic phaser tone with salon shop construction and components. Built on a pair of specifically-matched FETs for the highest degree of fidelity possible, this pedal shines as a subtle accompaniment that complements your tone with subtle shimmer and waves rather than overwhelming it with effect.
