Used Mad Professor Evolution Orange Underdrive

The Mad Professor Evolution Orange Underdrive is a unique pedal designed to reduce gain and clean up your tone without losing character or dynamics. Unlike traditional boost pedals, the Underdrive lets you dial back an overdriven amp to reveal crisp, clear notes while keeping warmth and feel intact. Simple controls for volume, tone, and drive offer easy sound shaping, making it ideal for balancing rhythm and lead tones or refining your amp’s breakup point.

This pedal includes its original box, and runs on a standard 9V DC Boss-type power supply.
