U2 - BOOSTER + OVERDRIVE

The pedal has nothing to do with the namesake band, although U2's Dave Evans might find it quite handy as a true overdrive/boost geek he is. "U2" is actually two separate pedals in one body. The classic overdrive with an active booster. It's quite a popular combination among guitarists. And it has many benefits. But the gimmick of this very pedal is the function that would be impossible when using two separate effects. It's the option of the following order. The first mode is when the booster is first and acts as the "heater" with a flexible timbre adjustment. The second mode is when the booster is preceded by overdrive. In this case the overdrive tone can be amplified and corrected (in frequencies) by the active booster.
