What is the best distortion pedal right now?

Fender's Pugilist Distortion is a hugely versatile dirtbox thanks to its dual distortion circuits, which allow you to blend two channels for monstrous high-gain tones with enhanced clarity – similar to playing through separate amps at once. As a result, it's one of our absolute favorites.

Alternatively, with all sorts of flavors of gain at your fingertips, with the Wampler Sovereign Distortion on your pedalboard you could lose days (weeks) just dialing in various tones, each bathed in harmonic-rich distortion and crunch. It’ll do metal nicely, with tight low-end, but the mid-contour can give your chords all the punch of a young Mike Tyson, too.

Best distortion pedals: What is distortion?

So, let's talk about what we mean by distortion and how this might affect your hunt for the best distortion pedal. As with anything with an aesthetic purpose, gear, and how it sounds, is subjective. There are no rules so long as the tone speaks to you - and ultimately, that's the most important thing.

This list focuses on distortion pedals, but naturally there’s some overlap between distortion, overdrive and fuzz, as all of them dirty up your tone. But where overdrive doesn’t change the fundamental character of your guitar’s signal, distortion is more aggressive. It clips your signal harder. Fuzz clips it harder still, so you really lose definition.

Distortion pedals are best applied to clean tones. Just stomp on the switch, and your metal/punk/hard rock dreams await. With that in mind, let’s talk about what you might be looking for...

Best distortion pedals: buying advice

In the world of heavy metal, distortion is the most-prized raw material, and the evolution of metal and its subgenres through the ages has seen the black t-shirt dollar buttressing the economy for high-gain pedals. For some metal players, a pedal that can deliver thick, saturated distortion, often with a tight compression to it.

If you are playing towards metal’s extremes, you’ll want a whole heap of distortion. Some scenes, such as early ‘90s Stockholm death-metal, coalesced around a single distortion pedal, the Boss HM-2; they dimed everything and it sounded horrible but brilliant in its own way

As a rule of thumb, however, it’s always good to use just enough gain to get the job done, and not to overdo it.

Features that can enhance a distortion pedal include its EQ, which lets you shape your tone (with three- and even four-band EQs being the gold standard), and imaginative switching options such as selectable clipping modes, which let you choose between different voices of distortion. A little versatility goes a long way, even when melting faces.

The best distortion pedals you can buy right now

Best distortion pedals: Fender Pugilist

1. Fender Pugilist Distortion Pedal

Set your dual gain engine running

Price: $120 | Controls: tone A, gain A, tone B, gain B, blend, blend on/off, bass boost, level | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Sounds excellent, tweak-able
It’s a steal at the price
High-gain outshines the crunch
Blend might cause confusion at first

Fender have stacked the Pugilist with all the gain you need, and even if it takes a bit of time to dial in your desired setting and negotiate the two gain channels via the blend, there’s so much joy to be had.

Yes, it can function as an overdrive, but we’re on the hunt for the best distortion pedals, and the Pugilist understands this, with oodles of gain that can be shaped to react to your pickups. 

Mode A is more overdrive/crunch; Mode B saturates the tone for a more modern metal tone, while the bass boost is excellent for fattening up single coil tones.

Best distortion pedals: Wampler Sovereign Distortion

2. Wampler Sovereign Distortion

One of the best distortion pedals around right now

Price: $199 | Controls: volume, mid contour, tone, gain, bright/even switch, gain/boost switch | Sockets: input, output, power | Bypass: relay true bypass w/ soft switch | Power requirements: 9V power supply, 9V battery

Hugely versatile tone control
Well thought-out gain structure
Expensive
Some sag with high-output pickups

Brian Wampler has packed a heap of features into a small enclosure here. The Sovereign could probably fight in the overdrive category but has so much beef in its gain structure that goes way beyond.

The Sovereign’s controls have changed name through the years – from “mid behaviour” to “mid contour” but their mastery over the pedal’s midrange and highs is ever reliable. The pedal’s soul lies in that mid contour.

The even/bright switch lets you toggle between more of a mids-heavy sound and top-heavy treble, while the standard/boost chooses between responsive overdriven tones and more gnarly levels of gain.

Best distortion pedals: MXR M75 Super Badass '75 Distortion

3. MXR M75 Super Badass '75 Distortion

An analog, affordable, classic from MXR

Price: $100 | Controls: output, distortion, bass, mid, treble | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Low noise, large output
Three-band EQ
Produces versatile analog distortion
Unconvincing at low and high gain extremes

Like the Sovereign, the M75 has a default voice that speaks in British EL34 tube crunch. Keep everything at noon to maintain that sort of equilibrium, but if you’re chasing heaps of ugly-delicious metal gain, roll it forward to 2 o’clock onwards.

The three-band EQ is everything in changing the character of the M75’s gain. Take out some of those mids for late ’80s Metallica scooped crunch, boost them for that ‘70s vibe.

When it comes to the best distortion pedals, the M75 is a no-brainer that takes seconds to find the tone you want – an indestructible little powerhouse of versatile analog distortion.

Best distortion pedals: HS Modded ProCo RAT ‘Pack Rat’

4. JHS Modded ProCo RAT ‘Pack Rat’

This legendary stompbox is still a filthy animal

Price: $70 | Controls: distortion, filter, volume, three-way mode toggle | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Excellent upgrade adds tone options
Epic sustain/harmonics, filthy gain
Close to fuzz at the extremes
Act fast, stock often runs low

Like the DS-1, the ProCat RAT is the stuff of legend, favored by James Hetfield, Thom Yorke, Dave Grohl… It has similarly been modded a thousand times. This Pack Rat model from JHS pedals upgrades the pedal and installs a three-way clipping selector for vintage, open boost and turbo RAT modes.

The character of the old LMN308 is here, but under the hood the components have been upgraded. The cheapo capacitors are gone, their replacements made from metal film and tantalum. There’s less noise. But let’s not kid ourselves, you can’t tame a RAT. Pure grind, rich and fizzing distortion awaits!

Best distortion pedals: Boss DS-1

5. Boss DS-1 Distortion Pedal

The original weapon of mass distortion

Price: $50 | Controls: level, tone, distortion | Sockets: input, output, power | Bypass: buffered

Excellent value
Classic gain structure
Easily modded
Mids can be thin

The Boss DS-1’s set-up is simple: level, tone and distortion, with a rubber-topped foot-pedal to switch it on and off. The pedal is happy adding a little crunch, some extra oomph, but it keeps the integrity of your guitar tone steady when dimed.

There’s plenty of versatility. The DS-1’s tone knob really can tweak your highs, perfect for pinch harmonics. Dial it back to thicken up you rhythm tone or to fatten up single coil pickups.

All this tone for under 50 bucks, what’s not to like? Just don’t underrate it just because it’s cheap and pre-dates the Sony Walkman.

Best distortion pedals: EarthQuaker Devices Acapulco Gold V2

6. EarthQuaker Devices Acapulco Gold V2

Here comes the Sunn…

Price: $129 | Controls: volume | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Loud and gnarly distortion
Simple to operate
Lack of EQ 
High-gain fuzz isn’t for everyone

The Acapulco Gold is dominated by giant output volume knob and its brief is devastatingly simple: to bring the power and tone of a Sunn Model T amp and house it inside a small pedal.

And it works: at low volumes, say, 9 o’clock on the dial, this works as a neat little overdrive, but keep turning it clockwise and the gain – and the volume – keeps coming. The final destination is a thick, fat and open distortion, with a little fuzz overtones, that makes for amazing ‘70s metal tones. 

Adjust your guitar’s tone knob to tease different voicings from the pedal. And wear earplugs.

Best distortion pedals: KHDK Dark Blood

7. KHDK Dark Blood Distortion Pedal

Metallica’s Kirk Hammett puts pedal to the metal

Price: $229 | Controls: gain, volume, doom, gate, hi/lo switch | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Supreme metal tone
In-built noise gate
It’s a lot of dough
You spent your money on wah

Metallica’s flamboyant lead guitarist knows his way around a distorted metal tone and the Dark Blood is one of the best distortion pedals thanks to a hefty tone modeled in the high-gain American tube amp style.

The gain is tight and thick, with plenty of bass response courtesy of the appropriately named “doom” control, which intuitively shapes your low-end.

You can find some really devastating rhythm tones setting the hi/lo switch to lo and tweaking said “doom” setting, but an onboard noise suppressor keeps things sane and there are plenty of sparkling highs to be dialled in on what is a great all-rounder for metal.

Best distortion pedals: TC Electronic Eyemaster

8. TC Electronic Eyemaster Metal Distortion

The best distortion pedal for death metal tones

Price: $95 | Controls: gain, volume | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Classic death metal tone
Simple design
Great value
A one-trick wolverine

Another small enclosure pedal of simple design housing an enormous and classic metal distortion tone: it must be a Boss? No, but the Eyemaster, named after the Entombed song, is unashamedly channeling the dimed Boss HM-1 Heavy Metal with equally dimed Peavey Bandit for that classic Swedish death metal sound.

Designed and built in Denmark, this pedal is indestructible, but it comes with a three-year warranty just in case.

Push it all the way for death metal nastiness, dark, raw fuzz energy. There’s just gain and level to play with, but relax, TC Electronic fixed the tone. They know why you’re here; you took the left hand path.

Best distortion pedals: Walrus Audio Iron Horse LM308 V2

9. Walrus Audio Iron Horse LM308 V2

Heavy beast by name, heavy beast by nature

Price: $199 | Controls: level, tone, distortion, three-way mode toggle | Sockets: input, output, power | Bypass: true bypass | Power requirements: 9V power supply, 9V battery

Switchable clipping options
Excellent gain structure
Takes a bit of adjusting 
Err, that’s about it

The Iron Horse V2 sees the unit updated with a more dynamic tone control and a new level control that makes it easier to dial in unity gain (i.e. when the pedal’s output level is the same as when it isn’t in the signal chain). The distortion circuit has been tweaked too for more subtle low-gain tones.

Key features include the three-way toggle switch that selects between clipping diodes letting you choose from slightly compressed to more compressed and totally open distorted tones.

The enclosure is finished with some neat artwork from illustrator Adam Forster. We’d love to see a craft beer tie-in.

Best distortion pedals: Diezel Herbert Preamp

10. Diezel Herbert Preamp

All-powerful boutique thunder in accessible pedal format

Price: $299 | Controls: midcut master, midcut intensity, normal master, gain, treble, middle, bass, presence, deep | Sockets: input, remote, to clean amp output, to power amp output | Bypass: true bypass | Power requirements: 12-18V DC power supply

Incredible metal amp tones
Switchable mids
It’s pricey – overkill?
Takes a bit of getting used to

The Herbert is not a distortion pedal in the purest since but it can sure be used as such. Taking the city-levelling tone of the Diezel’s 180-watt lead head and putting it on the floor, this is a sure-fire way of adding high-gain filth to your signal.

This stomp-box ain’t cheap but the amp it takes its preamp circuitry from isn’t either, and featuring the same dynamic EQ options as its namesake, the Herbert has incredible distortion on-tap.

Outputs let you send to a clean amp or alternatively through a power amp or effects loop.
