The Keeley DS-9 Distortion captures the sounds of two legendary '80s distortions, the SD-9 and DS-1, and presents them in a boutique presentation with features like a cutoff control for adding or subtracting gain, true bypass, and a relay circuit with toggle switch for easily moving between the two. Championing two of the overlooked distortion titans of yesteryear, the DS-9 gives you all flavors of Marshall and Orange-esque dirt with plenty of tweakable options.
