The Empress Heavy Menace is a high-gain distortion pedal from Empress Effects, an evolution of the company's original full-size Heavy in a smaller, pedalboard-friendly enclosure123. Empress describes it as covering any high-gain tone from crunch to crushing, with a three-band EQ, a footswitchable adaptive noise gate and a key input for triggering that gate from a separate signal4. It shipped from May 2023 at $249.00 USD41.

What sets the Heavy Menace apart from most compact distortions is the gate. Envelope followers in the circuit respond to your playing, letting sustained notes decay naturally but clamping down quickly during fast stops4. On Sweetwater's demo, Nick Bowcott put it this way:

"due to its adaptive circuit this gate responds exactly to your playing let sustaining notes Decay naturally while clamping down"5

The controls: Gain, Weight, Output, EQ and Gate

The Heavy Menace carries two footswitches: one for bypass of the drive sound and one to kick the gate in and out3. The knob set breaks down like this489:

ControlWhat it does
GainSets the amount of distortion8
WeightAdjusts a high-pass filter in the distortion circuit to shape low-end character4
OutputSets the level leaving the pedal3
Low, Mid, HighThree-band EQ, each with ±15 of cut or boost9
Mid FrequencySweeps the mid band from 200 Hz to 2.5 kHz to dial in the sweet spot for your guitar and amp4
Gate ThresholdSets the threshold for the footswitchable noise gate8
ChannelThree-position switch: Lite(ish), Heavy, Heavier4

The Weight control is the one players coming from other high-gain pedals will notice. Empress says turning it up gives a thick, full sound, while turning it counterclockwise gives a tight response suited to palm muting and extended-range guitars4. Delicious Audio called the result "a pedal that might win the contest for 'most tweakable distortion pedal in a compact case'"2.

Lite(ish), Heavy and Heavier modes

The three-position Channel switch selects between three voicings1:

  • Lite(ish): a lower-gain option for a more classic crunch. Delicious Audio describes it as slightly less heavy tones perfect for old-style hard rock and classic rock2, and Pete Thorn noted it lets you get into a lower gain range, more like crunch3.
  • Heavy and Heavier: the two voicings carried over from the original Heavy pedal, aimed at extreme saturation. Guitar World described them as working their way up the gain scale, promising searing modern metal sounds8, and Delicious Audio called them suitable for genres flirting with extreme distortion2.

The original Heavy offered just the two channels, Heavy and Heavier6, so Lite(ish) is the new ground the Menace covers.

The noise gate, key input and bypass modes

The gate is footswitchable, with a threshold knob to set where it engages410. Two bypass modes change how it behaves4:

  • Normal bypass mode: the gate doesn't affect the signal if the distortion is off4.
  • Independent bypass mode: Empress says this is like having separate distortion and gate pedals, so the gate can stay active on its own4.

The key input is the other gate feature worth knowing. It lets you trigger the gate from an external signal rather than the main input3. On Premier Guitar's demo, Zach Wish explained the use case:

"run that pristine clean sound into the gate key input on this pedal and it allows the gate to respond way better"7

Empress says this allows consistent gate operation regardless of changes at the main input, such as stacking pedals earlier in the signal chain1. Delicious Audio notes it is particularly useful with pedals placed before the Heavy Menace, such as a low-gain pedal for stacking, and that splitting a clean signal with a pedal like the Empress Buffer+ keeps the gate behaving consistently2.

For bypass itself, the pedal offers true bypass for maximum transparency, or buffered bypass to protect against signal loss over long cable runs42.

Power: 9V, 250mA

The Heavy Menace runs on a 9V DC center-negative supply through a 2.1mm barrel connector and does not run off a battery45. It requires 250mA4, which is more than many compact analog distortions draw and rules out sharing a low-current daisy-chain output. The original Heavy drew approximately 200mA on the same 9V DC negative-tip supply11.

The 250mA current draw means the Heavy Menace needs a power supply output rated for at least that. A typical 100mA isolated output will not run it.

Heavy versus Heavy Menace

The Heavy Menace is an evolution of the original Heavy with new features and a compact enclosure4. Pete Thorn, who demoed both, described the Menace as the compact version: "I did a video for the original version this pedal was a bigger pedal"3. The differences that matter to a player:

Empress HeavyHeavy Menace
ModesHeavy, Heavier6412Lite(ish), Heavy, Heavier4
GateNoise gate with natural and aggressive settings11Adaptive, footswitchable gate with threshold knob and key input410
EQ3 bands of EQ133-band EQ with sweepable mid frequency14
Current draw~200mA11250mA4

The Limited Edition

Empress also offers a Heavy Menace Limited Edition, listed at $249.00 USD12. It shares the standard pedal's enclosure height of 1.5" and 1lb weight12.

What reviewers said

Reception was largely positive. Premier Guitar's 2024 high-gain roundup described the pedal as "loaded with an immensely powerful 3-band EQ with a sweepable mid control, footswitchable noise gate, a low-end sculpting control, and three different distortion modes"14. Guitar Pedal X's Stefan Karlsson was more measured in his 2023 review, calling it "a decent pedal as all Empress releases typically are," noting he liked it and kept it in his reference collection but could not endorse it overall15. Empress lists Chris Wrate among the artists who use the Heavy Menace4; on his Empress artist page he calls it "an absolute beast of a pedal and can take any amp to a level you'd never think it could achieve"16.

On Premier Guitar's demo, Zach Wish ran the pedal through a 1968 Fender Bandmaster set clean with a Fender Jazzmaster HH and a Gretsch G5260 Electromatic Jet Baritone, noting the $249 price7.

Questions

Does the Empress Heavy Menace run on a battery?

No. The Heavy Menace needs a 9V DC center-negative power supply through its 2.1mm barrel connector and does not run off a battery. It draws 250mA, so it needs a supply rated for that current rather than a shared low-current output.

Is the Heavy Menace true bypass or buffered?

It can be either. The pedal offers true bypass for maximum transparency, or buffered bypass to protect against signal loss over long cable runs, so you can choose the mode that suits your pedalboard.

What is the gate key input on the Heavy Menace for?

The key input lets you trigger the noise gate from a separate signal instead of the main input. Feed it a split clean signal, from a pedal like the Empress Buffer+ or a tuner output, and the gate behaves consistently even when you stack other pedals before the Heavy Menace.

Is the Empress Heavy Menace analog?

Yes. The Heavy Menace has an all-analog signal path, with the distortion, EQ and gate circuitry handled in the analog domain.

What is the difference between the Empress Heavy and Heavy Menace?

The Heavy Menace is an evolution of the original full-size Heavy in a smaller, pedalboard-friendly enclosure. It keeps the Heavy and Heavier voicings, adds a new lower-gain Lite(ish) mode, a Weight control for shaping low end, a sweepable mid EQ and a key input for the gate.

How many Heavy Menace Limited Edition pedals were made?

Empress made 350 units of the Heavy Menace Limited Edition, announced for Halloween 2025 in an opalescent blue-purple sparkle colourway with custom graphics. It carried the same $249.00 USD price as the standard pedal.
