From what I've gathered, most people don't really like this pedal. Boss only made it for one year, and I bought mine secondhand from the Trading Musician in Seattle. In fact, it was so hated that when I had a $12 credit at the store, I offered to take that pedal in lieu of cash and they accepted. Here's the catch: On basically every setting, it sounds kinda lousy. The distortion is meant to be a hard/heavy metal kind of sound, but it just doesn't hit the sweet spot that someone playing that style is going to want. Here's the secret: Turn the volume up to max, contour knob to about 11 o'clock and all the others down to zero. Instant Blackface overdrive. In this setting, it has a bit of a scooped eq with some boost to the bass and treble. It's incredibly touch sensitive to picking dynamics, and will go from a clean strum to a nicely overdriven tube-amp distortion. Stick in front of a good sounding tube amp, clean or distorted, and your amp just sings. It's one of those pedals that you instantly feel disappointed when you turn it off, it makes everything sound that much better. Maybe mine is special and the rest are crap, but it won't ever leave my pedalboard from now on. EDIT: Volume to MAX volume. That's important. I was writing this based off of memory.
