This pedal has the name overdrive and distortion on the front. Many of the Boss pedals have either or but this one does have both. The reason being is that the color control knob is more of a saturation control knob. It isn't necessarily and gain knob but as you increase it it will give you more distortion and less overdrive. You still have a gain control knob and that of course controls the gain. But gain and saturation are two different things as to why I think they have included both names on the box.

This pedal is a great pedal when running the front of your amp or any an all out distortion box. Like I said in the beginning you ca set your color control knob to either give you distortion or overdrive. The further up the clock wise face of the control the more distortion you would get. As you roll it down or off you get more of and overdrive tone. Both are equally as appealing. They can fit in almost any style of music.
Use this pedal in front of an overdriven amp and you will get a nice booster type pedal and get some great rhythmic and lead tones. It works well in a clean amp too but I find that there is just something missing in a pedal wheres as a good boost will work wonders on your tone.
The thing I loved most about this pedal was that it did not sound like a pedal but rather natural amp distortion. If you run in into an overdriven amp i does well. I would recommend this pedal to anyone who uses cleaner amps or now overdriven amps who want a lower volume distortion or even slamming the front of your dirty amp. Great pedal!!! At new you can find these pedals for right at around $90. not a bad price for a good sounding and very usable distortion/overdrive pedal.
