Little Big Muff Pi : Heavy distortion

This is the first distortion pedal I've used and I'm starting to love it more and more every time I try it. The distortion is pretty heavy and muddy and even on lowest settings it's very fuzzy and dirty. The distortion is excellent for heavy rhythm playing - it's very dirty but has a good attack to it. I find it a bit too heavy for lead playing, although it works with a bit of tweaking on the tone and sustain. Power chords roar with it and the metal housing feels like it can take beating. The controls can give you a few options in tone but one should keep in mind that even with sustain turned down it's still pretty muddy.

Pros:

built like a tank

brilliant for heavy rhythm playing/power chords

massive sound

Cons:

a bit too much for lead playing

doesn't "roll off" at lower settings/not very dynamically responsive (very muddy even when sustain and guitar volume are turned down)
