this was the first big muff I ever owned circa '96.... I gutted mine and built another effect into the box. I had the intact and function PCB in the wooden box for a long time and recently I took it out and housed it in a spare box... plugged her in and Is till hate this pedal. This is one of the worst sounding muffs. I've realized I don't actually like big muffs, but even going past that distaste these black Russian muffs sound like ass.

I love this thing so much! It's hard to describe how it differs from the standard Big Muff; the fuzz is a little less thick (I mean that in the best way possible!). Just go look it up. The circuit in this thing is apparently nearly identical to the Bass Big Muff.

I use it to pretend to be Dan Auerbach...it's surprisingly versatile for other sounds/styles, though!

one of the best dirt pedals ever. not quite a fuzz, not quite an overdrive, not quite a distortion, but more of a mix of all of that in one with some outrageous sustain. Simply, I've got a ton of people listening to me play and wondering how im getting that really intense and then really gentle distorted sound that can get extremely fuzzy too. And when I say it's from the same pedal it blows people's minds. So glad I grabbed one of these back in the mid 2000s when they were 50 bucks and considered a cheaper, shittier version of the Big Muff. My my my how they were wrong.

I have went through numerous fuzz pedals trying to find the right one and this is the one I have stuck with the longest. I love this thing! I stacked it up against all the other Muffs and Muff clones I've had several times and it just kills all of them. It's big and rich with a smoother top end and more low end compared to normal Big Muffs. So what if it doesn't have a 9v input? So what if it's big and clunky? Considering how good of a sound you can get out of it, It's well worth it!

Version 8. I tried her in replacements with the rest Big muff. I a little her used on the stage.autumn2017. not a convenient entrance and exit. there are no power connections, the button sustein isn't conveniently located when you include you touch it and settings, but despite it at it a fine sound get off. perhaps one of the best in a ruler big muff.

This unit's in & out jacks, the easily-loosened tri-pole switch, and the curved shell without interior support make it unreliable under solid stomping. The sound, however, is as good as the legend is inspired.

The sound behind Iconic songs. With a hint of Russian.

Its not just a Big Muff Pi! Its darker, deeper and harder!

As I possibly could never get a green muff, this is the Black Keys kind of tone and it has one of the best tone knobs I've ever seen.

Have had this for 18 years and it still makes me grin like an idiot.
