Mad Professor · pedal
The Mad Professor Evolution Orange Underdrive works backwards from a typical overdrive: instead of adding gain to a clean signal, it takes an already-overdriven amp tone and cleans it up in a controlled way, similar to rolling back a guitar's volume knob but with more precision. A three-band EQ lets players cut or boost midrange, since that is where most of an amp's overdrive character concentrates, making it possible to dial an amp's drive down without losing its voicing. It is designed to pair with vintage-style single-channel amps that are pushed hard enough to break up on their own, giving players a way to access cleaner tones from an amp that is always driven.
