Electro Harmonix Big Muff PI Classic

As stated in the title, in this big box you won't find many different nuances of distorsion, but I really love the few tones you can get out of it. it's a creamy and thick fuzz distorsion, probably the most famous sound of 90s rock. Think about Nirvana's legendary wall of sound. I had to buy separately an adapter as the 9V plug is different from standard pedals. Besides that and the large footprint in your pedalboard, I guess this is one of the best sounding distorsion pedals at this price, and if you're on the rock side, sooner or later you'll have to try one of these. Build quality is good, feels solid and stable. I tried it on a Marshall JCM900 and sounded really good. You can also blend it with a modulation pedal (mxr phase90 ie) and has creamy, tasty vibes. Works like charm with a fender stratocaster, and quite good on a gibson les paul as well. A one trick pony that deserves your attention, for sure.

I didn't know much about fuzz pedals before I ordered this pedal.

I watched a couple of videos and its sound instantly reminded me of the black keys, a sound that I love. So I was instantly convinced that I needed this, although I was in the market for a distortion pedal.


Once I got it, I could dial in some heavy stoner fuzz tones, and I think I can pull off a pretty decent heavy sound now.


In my opinion this works very well for stoner rock, fuzzy psychedelic rock or almost hippie satanic metal... All of which I love, not good for metal though.

So I'm still in the market for a distortion pedal, cause I like to play metal every now and then.

I use this with a orange crush 20rt and it sounds good on the clean channel, but as soon as I put some overdriven gain from the dirty channel it just gets ruined.
Maybe it's not meant to be combined with a transistor amp. Hopefully one day I can test it with a proper valve amp.

Anyway, great pedal, it's inspiring me to come up with stoner songs, thank you electro harmonix.

The Big Muff Pi from EHX is a classic. You can make a great tone for your guitar only with this pedal and the controls you have on your guitar - Like Jack White did some times.

Been using it for years in my tone meant for solos, until I replaced it with JHS Muffuletta for more versatility. Also, if you are into Pink Floyd, you can get some tones reasonably close to some of Gilmour's with a single coil guitar.

The downside would be that it is quite a large pedal and it takes a lot of room out of your pedalboard. Also, the background noise is quite high. But you know.. it's a fuzz.

I love this pedal for its distinctive sound and its a great price for US manufacture.....!
It controls give a really wide sweep of the effect and it has that really great analogue feel that some newer types seem to lack..even though they are analogue!
I like that you can adjust those giant knobs on the fly with your foot!
Oddly,I prefer it through SS amps not tube..no idea why..!
Downside?..it doesn't actually feedback that easily though it sustains like crazy...
The switch went funny after about a years fairly heavy use...but as ,everything is so big and '70's and easy to take apart I found I was able to dismantle the switch and click the contacts back into place so its fizzing and fuzzing away nicely again...
Its no longer a fixture on my rig as I've started to use a Boss FZ3 instead but really its a pedal that's worth having around just to have fun and experiment with from time to time!

This pedal is just a super classic! Lovely tone, sustain and distortion. I get why it's considered a classic and a lot of bands use it.

I was looking for a better distortion in some of my musics. A better toned one. This was the solution and what a solution.

For those that don't know this pedal be careful, it has a low noise. The pedal isn't faulty it was just designed this way. The power input isn't the normal one (the one from the boss pedals and such) it is a mini-jack input power. Take that into account. In my case, I have cables for that so...

Amazing pedal. I won't be selling it in the near future!
