For players chasing lush, multidimensional movement, the Keeley OAXA Phaser delivers far more than a classic sweep. This isn’t just a phaser; it’s a dual-engine modulation powerhouse that creates rich, swirling textures by running two independent phasers simultaneously, each with its own LFO for impossibly deep, chorusing-like layers.
At its heart, the OAXA offers immense versatility through simplicity. A single switch selects between three distinct voices: the lush complexity of 10-stage phasing, the crisp, classic throb of 4-stage, and the creamy, hypnotic swirl of uni-vibe mode. This expansive range is controlled by just three intuitive knobs for Rate, Depth, and Mix.
Built for the modern rig, its true stereo operation is a game-changer. You can run the dual phasers in series or parallel, making it the perfect tool to place after stereo reverbs and delays in an effects loop for truly immersive, studio-sized soundscapes. Hidden Alt functions add a one-knob compressor for added sustain and punch, plus a low-end depth control to preserve warmth and body.
Built on Keeley’s award-winning Core platform, the OAXA masterfully blends the rich, organic texture of analog with modern digital precision and reliability. It’s the ultimate tool for transforming your sound—from funky rhythms and swirling leads to vast atmospheric pads—into a living, breathing entity.
