What we say:

The most famous fuzz pedal ever? We think it could be! There are a lot of fuzz pedal out there in the world but the Big Muff Pi (we'll sidestep the jokes) has an iconic tone that hasn't been bettered since its late 60s release.

You may be after the lead tones from The Wall; you may be coveting Billy Corgan's abrasive Siamese Dream wall of sound; you may be interested in carving out your own sound: whatever brought you to E-HX's most famous pedal, it doesn't disappoint! There is a LOT of gain on tap here and whilst lots of people talk about it's creamy sound, we think it can also sound very edgy and dominating: it's all about how you set the controls and you do get a lot of mileage out of those three knobs!

Subtle it is not: repeatedly era-defining it is! Get one for yourself and make your own entry into rock history.


  • True bypass
  • Singing sustain with attitude

Just a great fuzz effect.Play it through my Fenderstrat American standard.

John S. - 2/4/2019

Mean fuzz but can also be used as a overdrive sound if you dial it in right

I'd bought several other fuzz pedals trying to get a 'different' sound, but in the end, the only tone that satisfied was the Big Muff. There's a reason it's a classic. So happy I finally surrendered.

C.W. - 11/11/2012

it took two weeks to come because you didnt have in stock (although the website said you did) but when i phoned up the guy i spoke to was really helpful. gutted i didnt win that fender competition tthough :(

M.S. - 11/11/2012

the big muff pi is one of the best fuzz pedals on the market, awesome tone & sustain, best used at loud volumes. Its getting a lot of use at band practice!

I recently ordered 1 x Electro Harmonix Big Muff Pi <br/>From your company and I thought the standard of service was absolutely excellent. Your email response is amazing and the speed with which you deliver goods is exceptional as well as the price which was the most reasonable i could find on the internet. The pedal was my birthday present and i'm really pleased with it. I was really impressed that you gave me a time for delivery so I did not have to wait in all day ( which i don't really mind doing but sometimes delivery does not even turn up in some companies!!!!) and it was completely accurate. Well done! So many companies don't pay attention to these sorts of areas and it can make purchasing items online really <br/>frustrating. I will purchase again from you in future and tell all my friends about the excellent value for money and service.

Quality tones and build

G.Z. - 28/3/2012

The Electro Harmonix pedal provides brilliant distortion and I am especially pleased with the sustain control. Basic, simple to use and very effective.
