Description
The Electro-Harmonix Deluxe Big Muff Pi is a fuzz effects pedal that effortlessly combines tradition and innovation. A tribute to the classic three-knob Big Muff Pi, this pedal has been a cornerstone of rock guitar for over four decades, known for its sweet, singing tone and violin-like sustain. The Deluxe Big Muff Pi offers all the legendary sounds of the original NYC Big Muff Pi, with added features for those who seek more control and versatility.
This pedal introduces a MIDS EQ that allows unprecedented tonal shaping of the Big Muff distortion. The GATE function offers a new way to play the Big Muff, providing bursts of fuzz when you play and silence when you don't. The ATTACK control adds definition to chords and riffs without compromising the original Big Muff's tone. The BASS BOOST function reintroduces some low end when the TONE is set to its treble settings.
The Deluxe Big Muff Pi also features a foot-switchable Mids section, providing an instant cut through the mix. Even better, the Mids section is sweepable with an expression pedal, enabling you to create fuzzy wah-style sounds with ease. This pedal is the ultimate tool for any musician looking for a flexible fuzz.

Best of the best Fuzz
One of the best Fuzz pedals. You can create a variety of sounds either for studio recording or for gigs. Very good combination with other pedals (eg mxr custom badass78 or keeley delay-drive). Needs though a lot of experimentation in order to find the thin lines of good sound when using the mids feature. Once you understand how it changes the sounds, it becomes powerful.

Does the job of two or three pedals.
This is a really versatile fuzz/distortion unit that can even do fuzz wah with an expression pedal plugged in. It's a bit big for a fuzz pedal but does the job of two or even three. Noise gate is a big help too. Was a bit unsure when I ordered it whether it would be right for me - but it exceeded expectations.
Addendum Since writing the original review I have added an EHX expression pedal to this - and it produces some great fuzz-wah effects. Don't even need a wah pedal anymore.
Tons of felxibility, perfect for tweakers
I've had this pedal for 5 years, and it was my number one fuzz for most of that time. It might be a little unintuitive for a beginner, but there's serious flexibility in there, and it can cut through a mix very well. The parametric mids offer a lot of freedom to tweak and pair the pedal with any amp, and the noise gate is pretty useful. One of the footswitches is acting up however, which is a common complaint with EHX products, hence the 4 star review

A Versatile Big Muff Alternative
While this may not be the most pedalboard real estate friendly or boutique sounding Muff on the market, the Deluxe Big Muff makes up for it with the massive array of tones hidden inside of it. There is the regular Big Muff control panel but underneath is a bass boost switch, which when activated will beef up single coil pickups. There is a built in noise gate which is a big plus. As a result, I run the Muff last in my string of gain pedals so it quiets any noise coming from any of them when it is on. The attack knob does just that: adds more attack to your picking. Where this pedal really shines above the rest is the foot switchable Mids section. It allows you to dial in a scooped or boosted mid tones so that depending on your circumstances, you either sink into the mix or are right at the forefront. A handy tool for solos. Now it is a monster on your board but I think its a worthwhile investment if that's the kind of tone you're looking for.
Even better than the original Big Muff
With all of the added features (bass boost, mid boost, attack knob, noise gate) the Big Muff Deluxe is even better than the classic Big Muff.

Mentioned in this November 15, 2019 guitarguitar interview.
GG: Ah yes, I know exactly the one! That’s interesting! Ok, cool! And have you got any pedals at your feet, for a typical Dead Can Dance gig?
BP: I’ve got a lot of pedals. (laughs) My basic set up is, I use two stereo combos. I loop in my pedalboard through a Kemper profiler and I also use a BOSS ES-8, you know the switching system?
GG: Yes, I know the one.
BP: And it’s all MIDI-linked, so I can change all the effects and everything, just stepping through the switching system, through the songs, basically. I do it all at my feet, and the Kemper responds to that. As for the pedals, I have the Waza Craft Vibrato.
GG: Oh yeah! The (Boss) Waza Craft stuff’s amazing.
BP: Yeah. I have it on really subtle, really low. I prefer Vibrato to Chorus and it gives such a subtle movement, you know? Modulation to the string? So, I pretty much have that on all the time. And then I also use an Electro-Harmonix Super Ego. I use it almost more like an audio exciter, it’s a very subtle doubling which widens the sound a little bit.
GG: Got you.
BP: Then I have an Eventide H-9 for all of my modulated effects and then that goes through a Strymon Big Sky for all the reverbs.
GG: That’s a good set up! You don’t tend to go for the more distorted or fuzzy tones, do you?
BP: No, I mean, I use them in a couple of songs, and I’m got an Electro-Harmonix Deluxe Big Muff, which kind of covers all of the kind of distorted, fuzz sounds. To be honest, I prefer fuzz to distortion anyway.
GG: Yeah, you can sort of manipulate your fingers and get different results out of fuzz effects, can’t you?
BP: Yeh, yeah, it’s more forgiving, I think.
