Sporting a three-band EQ control, four programmable presets and sixteen separate settings emulating classic distortion pedals through the decades, the Line 6 DM4 Distortion Modeler packs enough features and technology for creating nearly any conceivable distortion. Able to go from a warm tube overdrive to a full on buzz saw with a few turns of a knob, the DM4 is immensely versatile and a welcome addition to any pedalboard in need of some edge.
