Keeley combines two completely different overdrive and distortion circuits to create four different drives in one box. The Blues Disorder has two switches that allow you to separate the tone control from the clipping section. By mixing and matching the Tone and Drive switches you get two hybrid sounds. With both switches up it’s a smooth, soft-clipping Bluesy Breaker. The BB side is a low gain, soft-clipping overdrive. With both switches down it’s a fuller sounding, hard-clipping OC Distortion. The clever design keeps the pedal a simple three knob overdrive with 4 unique sounds. Switch easily between buffered or true-bypass; whichever sounds best in your rig. The Keeley Blues Disorder Overdrive and Distortion is designed and manufactured entirely by Keeley Electronics in aluminum enclosure.
