Mad Professor Evolution Orange Underdrive
Equalizer
The Mad Professor Evolution Orange Underdrive adjusts level and frequency balance to obtain cleaner sounds from an overdriven amplifier.
Volume reduces the signal hitting the amp, while Midrange, Bass, and Treble shape the cleaner sound, with other settings allowing a midrange boost.
It is useful for switching to a cleaner accompaniment sound while leaving a single-channel amp set for overdrive.
