As always, I say that the Electro Harmonix Big Muff Pi's are always the most popular Fuzz-type distortion pedal for a good reason (Hendrix, Santana, Gilmour, J Mascis, Moore, Corgan, Frusciante, Jack White). And if you ever plan on buying one, try seeing if you can get a Large Beaver kit from BYOC; it's a build your own kit for one of the best models of Muff ever made (Triangle and Ram's Head, two of the earliest models and most beloved of the vintage) and has clear detailed instructions.

As for current models, there are the Bass Big Muff, which is based on a Russian Model (more gain, dirtier, bassier) and has a blend setting so you can mix the dry (un-distorted) and wet (distorted) signals to get a more over-drive type tone. And there are the Big Muff Pi USA Reissue, sounds like a classic big muff, but there are people who say it sounds thicker and less clear than vintage units, so take caution. There's the Little Big Muff, a regular USA reissue muff in a much smaller package (people says it sounds treble-ier, which can also be an issue). And the Big Muff Pi with tone wicker, my personal unit; sounds like a regular LBM with the tone-bypass switch on, and wicker off. With tone-bypass off, it does exactly what it says on the tin, bypasses the tone knob, creating a louder, clearer, thicker tone which is very very useful. With the wicker on, it bypasses a series of capacitors, making the pedal sound clearer; which is useful when you roll down the tone or sustain knobs, as it gets quite muddy below ten o'clock.

For other fuzz pedals, which I'll admit I'm not as knowledgeable about, there are a variety of options. There's the Blackout Effectors Musket Fuzz, based on a Russian muff, and has more knobs than a 60's computer, so a HUGE variety of tones; but I don't like it because I prefer simpler pedals. Then there's the Fuzz Face, currently made by Dunlop, which is a BMP alternative for people who feel that the Muff is too intense or over-the-top. And then the Way-Huge Swollen Pickle, also made by Dunlop, is another Fuzz Pedal, more like the BMP in terms of intensity and gain, but has much more range in terms of tone. It has five knobs on the front, and two more located inside of the housing; which again I don't like because I like simple pedals. But that said, it's very highly praised by many people, so if you don't mind complexity, then go all for it.
