Big Muff Pi Distortion/Sustainer

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!

Check out this fantastic Big Muff anime from the incredibly talented Japanese artist Nota.

Anthropomorphism, the attribution of human characteristics to an object, is highly prevalent in Japan with mascots giving living, often human form, to everything from fast food to computers.

While we can't say these are official Big Muff mascots or even the characters we imagine when we think about the various versions of the beloved Big Muff, there's no disputing the high level of creativity that Nota used when designing these imaginative beings.

Designed exclusively for left-footed guitarists, the Left-Footed Big Muff was created to improve the precision, accuracy and tone of left-footed players.

This is an April Fools’ Day story, but click here for more information on EHX’s Big Muff Pi.

In an industry dominated by right-footed players and right-footed gear, EHX felt it was important to develop a pedal specifically for the legions of left-footed players worldwide.

Notable left-hand guitarists include Jimi Hendrix, Paul McCartney, Kurt Cobain, Tony Iommi, Joe Strummer, Dick Dale, and Albert King.

Speaking about the launch, Mike Matthews, Electro-Harmonix’s founder and CEO, said: “This pedal will not only improve the overall tone of left-footed guitarists, it is also the perfect pedal for the right-footed player’s weaker left foot. A left-footed guitarist finally has the benefits that a right-footed player has always had with the Big Muff and EHX pedals.”

We are very pleased to inform you that Mike Matthews has been nominated for Vintage Guitar Magazine’s Hall of Fame. The category is “Innovators” and this is an unabashed solicitation for you to cast your vote for Mike, a guy who truly is one of the most innovative characters in the music equipment biz.

A hollow boast? Hardly! Here is a short list of just some of the innovations Mike Matthews has been responsible for in his career at the helm of Electro-Harmonix:

  • First product to introduce the age of overdrive: LPB-1 Linear Power Booster
  • First portable, battery powered, guitar amp; Freedom Amp
  • First to introduce feedback with a phase shifter: Bad Stone
  • First electronic flanger: Electric Mistress
  • First with an analog delay: Memory Man

Want to put some thunder down under and some junk in the trunk? Check out the “Fuzz Bass” effect. It’s been used by The Beatles (“Think For Yourself”), Sly & The Family Stone (“I Want to Take You Higher”), U2 (“Get On Your Boots”) and countless others.

Running your guitar into an Octave Multiplexer and any one of the Big Muff pedals generates a thick, distorted, sub octave that will shake the walls. The Octave Multiplexer uses an analog flip-flop circuit to produces a unique, fat, grainy sub octave tone.

Settings and sample video are below:

This is part of an interview in Guitar World Magazine with Phil Taylor, David Gilmour’s guitar tech.

GW: I notice David tends to use stomp boxes instead of rack-mounted effects. What is his reasoning?

PT: I think his general feeling is that while rack effects tend to cover a lot of areas, they don’t cover any of them particularly well. He feels that foot pedals such as a Big Muff tend to have more character.

GW: How does Dave achieve the classic sound that we hear on the solos of songs like “Comfortably Numb”?

PT: It think it’s just pretty much him. He is obviously using a couple of effects, like a Big Muff and a delay, but it really is just his fingers, his vibrato, his choice of notes and how he sets his effects.

In Effectology 14, pedal guru Bill Ruppert takes us on a journey to previously unchartered sonic territory. Using only Electro-Harmonix pedals and his guitar, Bill creates a series of “believe it or not” soundscapes. Whether it’s the sound of songbirds singing joyfully by a babbling brook or a vintage vinyl “lo-fi” recording complete with clicks and scratches, Bill’s mastery of effects will amaze you. As he says, “Never judge what an effect pedal will do by what you have heard it will do. Experiment and you will find new sounds not yet discovered!” Indeed!

With thanks to Michael-in-Paris we just discovered the Pommery Champagne house in Reims, France (photo via Wikipedia):
When there, be sure to get a tour of the cellar. That's where you'll discover their contemporary art collection, which features an installation work composed of a pair of Les Pauls, Big Muffs, Marshalls, and a lot of birds.

The gear is left plugged in, and the birds actually "play" the guitars when they land on the strings. Michael wasn't too keen about the bird guano on the instruments, but c'est l'art:

For more Big Muff Pi art, see Robin Rose's "Cypher" Exhibit, Washington, DC and also Big Fluff Pi vs. Music-Industrial Complex. For even more, see the Big Muff Pi page.

This summer, look for the new documentary film "It Might Get Loud" featuring Jimmy Page (Led Zeppelin), The Edge (U2), Jack White (White Stripes), and directed by Oscar winner Davis Guggenheim ("An Inconvenient Truth").

Here's how producer Thomas Tull describes it: "I wanted to see a movie that captured the essence of why people are so fanatic about the guitar. While there have been a lot of performance documentaries, this one is really about the relationship between these three men and their instruments. We tried to show what drives the artists, what got them passionate as players, what made them pick up the guitar in the first place."

As for me, I was especially chuffed to see the movie's trailer, which begins and ends with Jack White playing a hand-made instrument through a Big Muff Pi. The trailer also includes the White Stripes' "Blue Orchid," one of the first tracks to feature the then-new POG (recently replaced by POG2):

But that's not all! You'll also get a quick look at The Edge sharing a tender moment with his Deluxe Memory Man at the beach:

Thanks to Vicktor Stilling for pointing me to his music video for "Rock Scientists" by Danish indie band Gravy, with an opening cameo by the Big Muff Pi. Victor co-directed the video and tells us that it showed at SXSW.
SXSW Synopsis: "It took directors Victor Stilling and Mads Hjort 150 hours and lots of coffee to complete this partially animated, partially real life footage video. The video for 'Rock Scientists' is inspired by the featured band Gravy's 'naked to the waist' live performances (vastly popular among female fans). One of Gravy's two drummers is a highly skilled chef, and thus the idea of cooking up a rocking stew with all the bands' secret ingredients came to life. Have fun spotting the spicy references to Rock 'n' Roll History in the video."

Cheers to Jack Conte for "This Disaster," his latest 'videosong' -- I spotted a HOG, a Big Muff Pi, and a Tube Zipper (and for EHX shirts, check out the merch shop).

btw, Jack's videosong rules are: 1. What you see is what you hear (no lip-syncing for instruments or voice). 2. If you hear it, at some point you see it (no hidden sounds).

Robin Rose is a long-established painter specializing in 'encaustic' works[?], but back in 1979 he played guitar and synth for new-wave/punk band Urban Verbs (Warner) and regularly performed at clubs like CBGB here in NYC.

For Robin's new exhibit, titled "Cypher" (April 7-May 17, American University Museum, Washington DC, info/pics), he changes gears and revisits those roots.

"Ascendant" (below, starting top-right) captures the skyward joy that comes when you catch a good groove. Gearheads, from top to bottom: that's a 1965 Fender Stratocaster with reverse tremolo, gold guitar cable, Marshall 800 Lead Amp Head, 1960 Slant speaker cabinet.

"Isolation," the circular work on the left, is assembled from 50 guitar effect pedals, with interconnecting cables. Robin explained that each pedal is an independent entity (in reality, and metaphorically), and each is connected to its peers, but through a loop that never accepts external input or offers external output. So, we can use this to consider the social world, where social circuits can also loop closed and cut off outside contact.
Robin's daughter, a 16-year-old rocker, artist and Sonic Youth fan with Asperger Syndrome[?] color coded the pedals (note the rainbow gradation on the left side). Robin tells us: "When the decision came to arrange the direction of the pedals, she said 'there is only one way they can go, Pointing IN.' I asked why, and she replied 'that made them lonely.'"

And I catch that lonely vibe: I first imagine myself standing in the middle of a dream pedalboard, but then I realize they're all turned away from me.

We're honored that Robin placed the Big Muff Pi at the bottom-center position. Thanks to Hemphill Fine Arts for the introduction. Images courtesy of the artist and Hemphill. Photography by Brandon Webster.

Be sure to catch John Frusciante's comments on the English Muff'n in the April 2009 issue of Vintage Guitar Magazine: "The Electro-Harmonix English Muff'n tube fuzz has some really extreme EQ and a big, thick and meaty sound. I used it on the solo for 'Enough Of Me.' I turn the EQ up, but leave my guitar tone knobs down and use either the middle or neck pickup so the original source sound is really dark and plain. If you blast the tone controls on the effect, you get a really thick, beautiful sound that reminds me of an exaggerated Eric Clapton tone in cream, where you have this really smooth fuzz."

In addition to the English Muff'n, John has also toured and recorded with the Micro Synthesizer, Big Muff Pi (both USA and Russian), POG, Metal Muff, HOG, Holy Grail, and Deluxe Electric Mistress. That said, I'm sure you fru-heads are still going to email and tell me what I left out.

We recently discovered this hand-sewn Big Muff Pi cushion by German artist/maker Gwendolin Tñ¤gert. It immediately struck us as funny and wonderful. (Translated from the German: "Wouldn't you love to hug a Big Muff all the time? Now it is possible! A super cute large stuffed cushion in the form of the world famous guitar effects pedal BIG MUFF!")

However, there was a touchy complication: the Big Muff Pi is a registered trademark, and if we discover unauthorized uses of our trademarks, we're legally obligated to do something about it (we have no choice about that).

We're all too familiar with the endless lawsuits suffocating the world of music, and so we decided to do something different. Instead of threats, demands, and legal letters, we contacted Gwendolin, told her we loved her work, and offered a formal license in exchange for an option to purchase them at discount. So, rather than a new enemy we now have a new friend, and a beautiful Big Fluff Pi. Take that as a lesson, music-industrial complex!

(Thanks for the tip to 'Ned Flanders' over in the EHX forums)
