Used Mad Professor Royal Blue Overdrive Pedal With Box

The Mad Professor Royal Blue Overdrive delivers exceptional tonal versatility, spanning from subtle overdrive through aggressive distortion with minimal signal coloration. At its lowest setting, the Distortion control functions as a responsive EQ, while the pedal excels at producing dynamic, amp-like crunch that responds to pick attack and guitar volume adjustments. The transparent circuitry preserves your instrument's character, allowing precise shaping via independent Treble and Bass controls. Whether paired with a clean amplifier or one with slight breakup, this pedal introduces professional-grade expressiveness and responsiveness to your signal chain—a hallmark of high-end boutique design. This pedal is in good condition and comes with a box.
