When i first started playing, Kurt Cobain was the reason i bought a Boss DS-1. I couldnt get that pedal to work for me then, still cant now. That was when i learned the hard lesson. Years later, I did get a Small Clone which I know Kurt used, but i only got it because it was on sale and discounted because the only one left was the display model. However, the small clone works for me and has become an extension of my soul. It is the only pedal that has stayed on my board since I got it. All in all, you will (likely) never sound like the artist you are trying to immitate. But if you are just getting into effects, it is a good place to start.
