CM-2 Tube Overdrive adds a new dimension to your tone. Overdrive is meant to be transparent and responsive to your touch and the CM-2 Tube Overdrive offers this with two modes of operation: Classic and Modified. Classic is transparent and articulate while Modified adds more gain and a "bigger" low end. As with all HardWire pedals, the CM-2 is crafted from premium all-metal components to perform night after night, tour after tour.
