The perfect bass fuzz?
This is the fuzz I have been searching for for years. The blend knob lets me dial in exactly the right amount of fuzz into my signal. The crossover switch lets me sculpt the tone from subtle EQ shift through to crazy synth like weirdness. It’s just perfect!

Good!
You can get a lot of cool tones out of this pedal alone! The blend knob makes it very eazy to keep some low end in the drive.

Secret weapon of a lead pedal
It says it's a bass pedal. It sounds awesome on bass too. I use it on guitar. Yes, it sounds a lot like the bubble font Big Muff we all had in 1997. However, the crossover controls make this thing a valuable lead pedal. If you like the Russian Muff sound, this pedal has that (It's probably my favorite new age EHX Muff clone), but you can set the crossover knobs to give you a cocked-wah sound that makes your tone poke through the mix for leads.

Perfect if you need a killer muff, and a bunch of other stuff too...
This pedal sounds awesome. So easy to dial in serious fuzz. Add to that the LPF/HPF, Noise gate, and DI out, and you have a veritable swiss-army knife in a pedal. I thought I wanted that, but ended up getting dedicated pedals for all those other jobs, and this became just a fuzz pedal that took up a lot of space on my board. But if you want a one-pedal solution, this may be just what you are looking for.
