Mad Professor Royal Blue Overdrive Handwired

The Mad Professor Royal Blue Overdrive Handwired is a premium, hand-assembled overdrive pedal from the Handwired Series, built in Finland with quality through-hole components, Alpha pots, Switchcraft jacks, and a rugged metal enclosure. It delivers a wide range of gain from smooth, light overdrive up to aggressive distortion, with limited filtering to preserve transparency and tonal clarity. When the Drive control is turned down, the pedal functions as a boost with EQ, giving players versatile tonal options.

Characterized by exceptional touch sensitivity, this overdrive responds dynamically to picking strength and guitar volume, offering expressive control similar to a boutique tube amplifier. The top-mounted jacks save pedalboard space and the true bypass switching ensures clean, unaffected signal when disengaged. Whether used for blues, rock, or more driven sounds, the Royal Blue Handwired adds responsive, transparent overdrive to your rig.
