KMA Machines Dead Stag

The KMA Machines Dead Stag is a distortion and fuzz pedal built around the Big Muff family of circuits. KMA describes it as "based on one of the most classic discrete fuzz/distortion circuits in pedal history," reworked into "a Big Muff style pedal, but one with many more tonal options and smart features"¹. Pedal of the Day put the same idea in plainer terms: "The Dead Stag is a Distortion, yes, but it's also a Fuzz, so you get the best of those two worlds in one slick enclosure"².

The pedal is discontinued. KMA lists it as a legacy product and states plainly on its product page that "This legacy product is DISCONTINUED"¹, so anyone wanting one is looking at the used market.

A Big Muff-family distortion and fuzz

The Big Muff circuit the Dead Stag draws on has a long history. Electro-Harmonix catalogs its Big Muff-family pedals, from the Triangle Big Muff Pi reissue to the Sovtek Deluxe and Deluxe Big Muff Pi, all as "Fuzz / Distortion / Sustainer"³, and the Big Muff Pi itself is described as a distortion/sustainer⁴³⁵. KMA Machines calls the Big Muff one of the most classic discrete fuzz/distortion circuits in pedal history¹, and the Dead Stag is built on that circuit: a Big Muff style pedal with more tonal options and smart features, a distortion that is also a fuzz¹.

KMA's take on that circuit is not a straight clone. In an interview with guitar.com, KMA's Enrico Preuss described the Dead Stag as featuring "a Red Army Overdrive-based circuit"⁶, pointing at the Russian-made branch of the Big Muff family rather than the familiar New York versions. What KMA built on top of that foundation is an EQ section that goes well beyond the classic three-knob Muff: active treble and bass controls, a fully parametric mid band, and internal bandwidth shaping¹².

Pedal of the Day's review captured the appeal in its own words:

The controls: six knobs

The Dead Stag puts nearly everything on the top of the pedal. KMA notes that "Apart from the internal Q Bandwidth control, every EQ control is on top of the pedal"¹. Two footswitchable toggles sit alongside the knobs.

The two toggles shape the character of the gain itself:

• High/low gain switch: KMA says it lets you "choose between two gain levels"¹. Pedal of the Day describes the choice as "either a low gain or a thick, high gain type of distortion"², and Delicious Audio's roundup of Big Muff-family pedals says the high setting "cranks up the distortion to extreme levels"⁷.
• Smooth/sharp switch: KMA describes it as giving "your high mids a boost at the end of the circuit"¹, which Delicious Audio frames as "a high mids boost for added clarity"⁷.

The parametric mid section is the feature that most separates the Dead Stag from a stock Big Muff. A classic Muff scoops the mids and offers no way to change that; here, the Mids knob picks where the mid band sits between 400Hz and 2.4kHz, the C/B knob cuts or boosts that band by up to 12dB, and the internal Q control narrows or widens the band itself¹². For a player whose Muff-style tone disappears in a band mix, that mid control is the working answer.

Power and setup

The Dead Stag's Gain toggle lets you choose either a low gain or a thick, high gain type of distortion⁷, so it covers both lighter crunch and heavier saturation without touching the rest of the controls.

Where it sits among KMA's other pedals

The Dead Stag was part of a run of KMA Machines high-gain pedals built around classic circuits. The company's later Guardian of the Wurm and Wurm 2 pedals take the Boss HM-2 circuit as their starting point instead of the Big Muff, and the Chief Disruptor, which followed the Dead Stag, is KMA's own expanded interpretation of the Muff format⁷. Against those, the Dead Stag remains the one aimed squarely at players who want a Muff-style fuzz and distortion with a full parametric mid EQ and switchable gain levels¹².
