My very favorite distortion ever, from overdrive to Marshall in a box. Just amazing

The Friedman Dirty Shirley overdrive pedal crams all the British-style grit, supple touch sensitivity, and tonal flexibility of its namesake all-tube amplifier head into a pedalboard-friendly enclosure. You'll be eliciting the same sweetened tone no matter what amp you run it through, thanks to six knobs that mirror the amp's controls. On the side of the Dirty Shirley pedal, Dave Friedman included a Tight switch to reign in your amp's low end when being pushed. The Dirty Shirley amp is a favorite at Sweetwater. Put that same sound into your rig with the Dirty Shirley overdrive pedal.
