The other day I was browsing some pedals and came across some fuzz pedals. After hearing some demos I thought to myself "Whats so different with these pedals than some normal overdrives?". I'm confused. Can't you get those tones by just running an overdrive pedal, lifting the gain, and rolling down the tone?

fuzz and overdrive are 2 different things. yes you can get a distortion sound with an overdrive but it's not quiet the same as fuzz. fuzz is an early form of distortion which is based on a square wave (sound form and sorry I can't explain it maybe someone else can). if you listen to 60s and early 70s rock you'll hear the difference,. check say the stones Satisfaction.

occasionally you'll find a pedal that will (sort of) do both

most of the time, not so much. the circuits are a fair bit different. if you want a fuzz, get a fuzz.

fuzz generally has way more overtones, clips the signal to almost square wave output and is far more compressed sounding (less dynamic, more flat volume response). fuzzes are very colorful distortion devices that tend to change your town quite a bit.

overdrives are generally used to make you amp sound a bit more driven, you usually want them to be fairly transparent sounding. OD's can be a bit colorful, but don't generally have such a large impact on your tone.
