The MXR Black Label Chorus is Zakk's secret weapon to thicken up his wall of distortion and add liquid dimension and texture to clean passages. At the heart of the Black Label Chorus is its bucket brigade circuitry—the only way to get truly rich and warm analog chorusing. Its vintage style tones are dialed in by High and Low cut filters and Level, Rate and Depth controls. For the ultimate in spatial chorusing, hook up two amps via the two outputs for a wide and sweeping stereo spread. Like all MXR pedals, the Black Label Chorus comes in a heavy-duty housing with durable jacks and switches for a lifetime on the road.
