This pedal is amazing for multiple reasons...
At a low setting, it can give you some really nice tube screamer-esque tones to break up your amp. It can also produce very driven, almost distortion-like tones. It has a a variable EQ, allowing you to get some very quacky, midrange sounds for country; some really trebly sounds, that really bring out harmonics and also some more bluesy, bass sounds. If I could have just one pedal, It would be the dude; it is extremely versatile and excels in all aspects
