I wanted to buy a good distortion pedal and a lot of people recommended this one, so I bought it.
So far I am not disappointed. It's brighter and more aggresive than my SD-1 overdrive pedal (which I use for older styles of rock), making this pedal ideal for post-60's style of rock, punk, grunge and metal to some degree, making it pretty versatile.
Also, I read somewhere that Kurt Cobain used this pedal, so there's that.
