The Keeley Phase 24 is a gorgeously simple phaser delivering 2 and 4 stage phasing for those very classic sounds. The Keeley Phase 24 offers shimmering and subtle watery tones for those wanting high fidelity and quality in a Keeley Engineered product. Part of the magic in this style phaser is a result of carefully matching FETs so that you capture excellent rounding of the phase sounds and each stage works together in harmony to bring you a full lush tone. A unique 2/4 stage selector gives you control over making this a classic 4 stage phaser or the less common 2 stage phaser for very subtle shimmer that you can use any time. A Depth control gives you further control. Think of it as a blend control allowing you to go from dry, no phasing to full depth, lush phasing.
