Whac-a-Muff: 3.8 Trillion Analog Fuzz Pedals in One Stompbox
Hangman Effects' Whac-a-Muff delivers 3.8 trillion analog fuzz variations in one stompbox with digital control and 127 MIDI presets.

Hangman Effects is tackling guitarist decision paralysis head-on with the Whac-a-Muff, a digitally controlled analog distortion and fuzz pedal heading to Kickstarter with 3.8 trillion circuit variations.
If you have ever stared at a pedalboard wondering whether you need a Triangle, a Ram’s Head, a Russian Green, or an Op-Amp fuzz—and briefly considered buying all four—Hangman Effects has bad news for your wallet and great news for your tone.
Rather than releasing yet another single-flavor clone of the world’s most modified fuzz-distortion circuit, the boutique builder has unveiled The Whac-a-Muff, a stompbox packing a staggering 3.8 trillion distinct analog circuit variations into a single enclosure. Yes, trillion with a T.
Born Out of Pure Pedal-Builder FOMO
According to Hangman Effects, the Whac-a-Muff wasn't born in a sterile lab—it was born out of good old-fashioned gear FOMO. While recreating classic circuits isn't usually the brand's bread and butter, watching seemingly every pedal company on earth release its own signature Muff-style mod eventually sparked an existential question: What if you didn't have to pick just one?
Instead of settling on a single resistor swap or clipping diode tweak, Hangman Effects engineered a platform designed to house virtually every conceivable permutation of the classic distortion, fuzz, and overdrive topology at once.

100% Analog Grit, Digitally Controlled Madness
Before analog purists reach for their pitchforks, there is a crucial catch: your guitar signal never gets digitized. The Whac-a-Muff features a 100% pure analog signal path, using digital switching strictly to reconfigure the analog components under the hood.
Those 3.8 trillion combinations span everything from microscopic component adjustments to full-blown circuit surgery, including:
- Subtle component swaps across resistors and capacitors
- Complete tone-stack revoicings and full tone bypass modes
- Voltage sag for dying-battery sputter and voltage boost for massive headroom
- Built-in oscillation for players who consider "uncontrollable sonic chaos" a primary genre

A "Random" Button for Infinite Tone Roulette
To help players navigate roughly 475 times more fuzz tones than there are human beings on Earth, Hangman Effects added a feature that sounds equal parts genius and dangerous: a Random button.
One tap scrambles the pedal’s analog parameters into a completely fresh circuit configuration. As the builder notes in the pre-launch demo, you could mash that button every day for the rest of your life and still never make it halfway through the pedal's library.

127 MIDI Presets—And an Unexpected Ableton Trick
For gigging musicians who prefer repeatable setlists over chaotic knob roulette, the Whac-a-Muff ships ready to work straight out of the box with 12 onboard presets modeled after the 12 most iconic historical versions of the circuit.
Hook it up to a MIDI controller, and storage expands to 127 recallable presets with full parameter control. Even better, Hangman Effects added MIDI output—so when you aren't melting faces with analog fuzz, you can use the pedal's tactile button grid as a makeshift MIDI instrument or Ableton Live clip launcher.
When Does the Whac-a-Muff Kickstarter Launch?
Hangman Effects has opened pre-launch sign-ups ahead of the full Kickstarter campaign rollout, teasing special collector reward tiers—including golden sparkle editions—for early backers.
Between its pure analog signal path, studio-ready MIDI integration, and enough fuzz combinations to outlast the sun, the Whac-a-Muff is shaping up to be the ultimate cure for fuzz-pedal hoarding.

What makes the Whac-a-Muff different from other Big Muff clones?
Instead of a single circuit variant, the Whac-a-Muff packs 3.8 trillion analog circuit permutations into one enclosure. Digital switching reconfigures the analog signal path without digitizing your guitar tone, offering everything from subtle component swaps to complete voltage sag and boost modes.
Is the signal path digital or analog?
The guitar signal remains 100% analog throughout. The pedal uses digital control exclusively to reconfigure the analog components—resistors, capacitors, clipping diodes, and tone stacks—beneath the surface.
How many presets does it have?
The Whac-a-Muff ships with 12 onboard presets modeled after iconic historical circuit versions. When connected to a MIDI controller, it expands to 127 recallable presets with full parameter control via MIDI.
Does the Random button actually help explore all the tones?
The Random button scrambles the analog parameters into a fresh circuit configuration with every press. Hangman Effects notes you could press it daily for your entire life and still only explore a fraction of the available combinations.
