The Dirty Shirley Overdrive from Friedman is a boutique circuit that packs the flexibility and harmonically rich tones of the all-tube, single-channel Dirty Shirley amp it's named for into a pedalboard-friendly package. It features the same intuitive control set as the amp, giving players the ability to dial in everything from high-output cleans to thick and gritty overdrive. For an even punchier tone that really reigns in the low-end, flip the Tight switch mounted to the side of the pedal to clean things up and bring back that special percussive attack.
