The original Mad Professor pedal returns! Twenty years after its debut, the legendary Little Green Wonder is back and in the updated Handwired series.

This high-headroom overdrive and booster delivers a specially tuned EQ curve and focused drive that pairs effortlessly with any guitar or amp setup. Thanks to its versatile Body control, you can easily tweak the tone whether you're playing single-coils or humbuckers. Plus, with bags of gain available, it works brilliantly as a standalone overdrive, stacked alongside your favourite drive pedals, or pushing an amp over the edge.

Faithful to the original circuit, this updated version includes all the premium upgrades of the Handwired series: high-quality through-hole components, Alpha pots and switches, and Switchcraft jacks, all packed inside a rugged sheet-metal enclosure with top-mounted jacks.
