The Dirty Shirley is a great amp in a box version of the amp of the same name. You have a good degree of control with Bass, Treb, Pres, Vol, Mid and Gain controls. Also there's the Tight knob on the side of the pedal. This is great at dealing with the Mids and Lows and prevents too much darkness or other tonal elements you're not satisfied with. Although it's a lower gain pedal you can still get a good amount of overdrive on the upper end of the scale and boost when Gain is rolled back.
