Constructed with a super compact all-metal chassis for durability and maximum pedalboard space, a reduced-size three-knob layout of the same tone, level, and drive controls, and a four-way internal dip switch mode selector for altering the clipping configuration, the Keeley Red Dirt Mini Overdrive takes expansive boutique-quality features and compounds them into the tiniest of packages. Originally conceived when working in tandem with John Petrucci, the Red Dirt serves up the same type of mid-gain roar as a certain green monster with a customizable edge all its own thanks to the array of built-in features. This pedal is a great candidate for those interested in adding more muscle and character to their overdrive section without overcrowding the board or as a primary overdrive on smaller effect sections.
