For years, dialing in a truly flexible Big Muff tone meant picking your battles. You got that thick, singing sustain, but shaping anything beyond Volume, Tone, and Sustain simply wasn’t on the table.
That changed when Electro-Harmonix quietly resurrected a long-lost dual op-amp Big Muff circuit and gave it the full treatment. The result is here now, and it’s called the Deluxe Big Muff Pi 2.
The Quick Take: If you’ve ever wanted a fuzz pedal that doubles as a parametric EQ and a wah, this is the closest a Big Muff has ever come to pulling that off.
What Is the Deluxe Big Muff Pi 2, Exactly?
At its core, this is EHX’s flagship take on a rare dual op-amp Big Muff circuit that was nearly lost to history before JHS Pedals’ Josh Scott dug up the original schematic.
EHX took that punchy, aggressive fuzz and stacked on a Blend knob, a noise gate, a three-way Wicker switch, and a fully footswitchable parametric mids section. It’s exactly the kind of tone-shaping depth we look for when we rank the best distortion pedals on the market.
The Spec Breakdown
Here’s what you’re actually paying for, no marketing fluff:
| Feature | What You Get |
|---|---|
| Circuit | Dual op-amp analog fuzz |
| Core Controls | Volume, Tone, Sustain, Blend, Gate |
| Tone Shaping | 3-way Wicker switch, footswitchable Mids (Freq, Level, Hi/Lo Q) |
| Expression | EXP input for external pedal or CV control of Mids Freq |
| Bypass | Buffered, with latching/momentary footswitch action |
| Power | 9.6VDC adapter included, 45mA draw |
| Size | 5.75″ x 4.75″ x 2.5″ |
| Street Price | $188.20 |
“This is the Big Muff we’ve all been waiting for!”
The Missing Piece EHX Isn’t Talking About
Every press release has a gap. Here’s ours.
- Buffered, not true bypass. If you chain several vintage-style fuzzes together, test this in your own signal path before committing.
- No expression pedal in the box. That wah-style mids sweep sounds incredible in demos, but you’ll need to buy a controller separately to use it.
- It’s a big footprint at a big price. 5.75″ x 4.75″ x 2.5″ eats real pedalboard space, and $188.20 is roughly double what an entry-level Big Muff costs.
How Does It Stack Up Against the Competition?
If you already own a standard three-knob Big Muff and rarely touch anything beyond Sustain, this won’t change your life.
But if you’ve outgrown that entry-level fuzz and keep reaching for a separate EQ pedal or wah to finish your tone, this is the upgrade you’ve been waiting for.
It’s also worth thinking about where this sits in your signal chain. Players who already lean on a solid delay pedal and reverb pedal are the ones most likely to notice everything the Mids section adds.
Who Should Actually Buy This?
✅ Buy This If…
- You’re a home studio builder who wants one pedal to cover fuzz, EQ, and wah-style sweeps instead of three.
- You already own an expression pedal or CV controller and want to put it to real use.
- You’ve maxed out a standard Big Muff and need more control over mids.
❌ Skip This If…
- You just want classic, no-frills fuzz — the standard or Nano version saves you real money.
- Your pedalboard is already packed.
- You run true bypass only and won’t compromise on that.
At $188.20, the Deluxe Big Muff Pi 2 isn’t an impulse buy, but it might be the last fuzz pedal a lot of tone-obsessed players ever need to add to their board.
