Mad Professor Evolution Orange Underdrive pedal First introduced in 1956 alongsideMad professors Evolution Orange Underdrive is a relaly intriguing pedal. Instead of pushing your tone like a traditional overdrive, the EOU works by lowering the midrange as that is where the overdrive mostly is. You can dampen the amplifier input with the EOUs Volume control and then set the Bass and Treble to tailor your clean tone. EOU can also be used to boost mids by setting the Midrange and Volume up.
