The Dirty Shirley Overdrive pedal delivers tube like tone in a small pedal format which can be used either into a clean amp or to boost an already over-driven amp. If your amp, or other overdrive gets a bit loose in the low end, throw ON the Dirty Shirley's Tight switch to bring back the percussive attack you crave.
• Friedman Dirty Shirley amp tone in a compact pedal format
