You’ve heard of an Overdrive pedal, something that adds gain to the single to push your tube amp’s preamp tubes harder and create singing distortion, well this is the opposite, hence the name Underdrive! The Mad Professor Evolution Orange Underdrive pedal lets you get cleaner tones from your favourite overdriven tone, which means if you have a single channel amp it is like adding a clean channel in a pedal. Some people might ask why do it this way around? Well this means you don’t have to sacrifice the amazing overdrive tone you might be getting from your amp’s tubes by setting it clean and boosting with a pedal. You might also say well you can already do that by rolling down your volume control, well here is Mad Professor’s answer:

“When you turn down the volume from your guitar to clean that tone, the sound often gets bit too dark and the clean tones are not as good as the overdriven tone. With EOU you can tailor your cleaner tone with the four pots. The Evolution Orange Underdrive works by lowering the midrange as that is where the overdrive mostly is. You can dampen the amplifier input with the EOU’s 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.”
