The Mad Professor ‘Evolution Orange Underdrive’ pedal offers a new way to approach tone. Instead of overdriving the clean tone from guitars, players can now get cleaner tones from overdriven tone. That is what Mad Professor is calling underdriving.

Evolution Orange Underdrive works really well with vintage single channel amps that sound great when players push them to overdrive. When players turn down the volume from their guitars to clean that tone, the sound often gets a bit too dark and the clean tones are not as good as the overdriven tone. However, with the Evolution Orange Underdrive players can tailor their cleaner tones with the four pots.

The Evolution Orange Underdrive works by lowering the midrange as that is where the overdrive mostly is. Players can dampen the amplifier input with the pedal’s Volume Control and then set the Bass and Treble to tailor the desired clean tone. Evolution Orange Underdrive can also be used to boost mids by settings the Midrange and Volume higher.
