From the manufacturer

Product description

The NYC original. Hendrix and Santana were among the first to get a piece of the Pi, and for over 40 years the Big Muff Pi has been defining the sound of rock guitar. Revered by contemporary guitarists and rock legends for its rich, creamy, violin-like sustain, from Pink Floyd to The White Stripes, everyone still wants a piece of the Pi!

Reviewed in the United Kingdom on February 18, 2018
Big dirty and fuzzy - if you are looking for a fuzz pedal, then quite simply this is the best one - period.
From dark muffled to high and fizzy, the amount of different usable sounds from this behemoth is astonishingly impressive.
Cranking the volume knob causes everything to start to fall to bits - the signal begins to degrade and your neighbours and local wildlife will run to the hills - meanwhile you will feel like a guitar god.

Turn everything down a bit, and the sound cleans up nicely but holds an amazing warm tone with fuzzy dirt on the end when you get a little to excited.

Don’t hesitate - buy one today!!!
