Replacing a pedalboard with a single pedal would have been unthinkable for most serious guitarists 10 years ago, but even the most exacting of pros are ditching the standalones for floor processors. If an enormous reduction in the size of your rig sounds mouth-watering to you, our guide to the best multi-effects pedals will definitely be of interest.

When digital processing became powerful enough to emulate digital-sounding effects and organic, analog effects, the arrival of multi-effects truly began. 

Though early units such as the Zoom 505 hardly set the world on fire, advancements in modern guitar tech have allowed them to make a serious comeback. With that in mind, we think the multi-effects pedals listed here are well worth your consideration.

These days, it's common for multi-effects to offer amp and even cabinet modeling as well as guitar effects. Although it's worth keeping these in mind, for the purposes of our best multi-effects pedals guide, we'll be focusing heavily on the effects side.

Best multi-effects pedals: Our top pick

In terms of both cost and its power, our number one choice for the best multi-effects pedal is the Line 6 HX Effects. All right, so without a screen it lacks some of the complicated functionality of the larger pedal... or does it? Instead, having a layout that's physically on the pedal and intuitive makes this Line 6 a joy to use, in addition to being a powerful stereo effects unit. 

If you don't need all the amp models and additional functionality of the larger Helix floorboards, it's a complete no-brainer.

Best multi-effects pedals: Buying advice

The most important things to look for in a multi-effect are ease of use and its bank of effects. After all, if it's not easy to use, it's unlikely to be as useful a tool, and certainly nowhere near as much fun.

Different multi-effects units focus on different sets of effects. Some stick closely to basic versions of staple sounds like delay, modulation and reverb, but many others also try and throw in a few wildcard effects - the kind you'd normally have to shell out big bucks for on boutique FX pedals.

It's also worth considering how many parameters the unit typically offers per patch. Generally speaking, the more powerful the unit, the more parameters it offers. This can be a double-edged sword, however, as too many parameters can lead to option paralysis, where the number of available settings can be overwhelming.

You might also be thinking, 'Why digital multi-effects?' Well, the simplest answer is that making many analog effects fit in a small space is very difficult in terms of circuit design. Plus, ordering and re-ordering those requires a digital 'brain' to control the routing anyway. 

That means, at a certain point, it's easier to do the whole thing in software. However, analog multi-FX floorboards do exist from Tech21, Mooer and T-Rex, among others. Let's take a closer look at the best multi-effects pedals for guitarists... 

Best multi-effects pedals: Product guide & reviews

Best multi-effects pedals for guitarists: Line 6 Helix HX Effects

1. Line 6 HX multi-effects pedal

This small and mighty multi-effect puts incredible power at your feet

Price: $599 | Number of effects: 104 | Number of assignable footswitches: 6

Feels great to use
Great range of effects
Not what you're looking for if you want amp modeling

With no screen, the HX Effects relies on scribble strips and colored lights above the footswitches in order to indicate what's going on to the user and to edit patches.

It sounds like that shouldn't be enough to compete with the larger units, but this stripped-back interface is elegant, and packs all of the effects of its larger brothers. This means that it has all the firepower to make it the best multi-effects pedal you can buy, particularly if you play live.

Moreover, besides the standard delays, mods and reverbs there's also some gems like the particle verb, which is a clear nod to boutique effects.

There are only six patches available on the front panel, but if that's an issue then you could always integrate it into a traditional pedalboard setup. It's not drastically more expensive than a single Strymon big-box pedal, and size-wise it's about twice the size of a Whammy.

Best multi-effects pedals for guitarists: Boss GT-1000

2. Boss GT-1000

Want all the 500 series pedals in one? Here you go...

Price: $1,049 | Number of effects: 145 | Number of assignable footswitches: 3-8

Huge range of effects
Impressive sound quality
Editing patches isn't super intuitive
Pricey if you're not using the amp models

Boss has been the market leader in compact effects pedals since the early ‘80s, and chances are, if you're reading this, you own at least a couple yourself. 

With its recent 500 series of studio-grade pedals - the DD-500 delay, RV-500 reverb and MD-500 modulation - the company brought its expertise to a new form-factor and a higher-ticket area of the market. If you looked at the release of those pedals and thought "if I had a board of just those three, I'd be set," you'd be far from alone, and that's exactly what the GT-1000 delivers.

Obviously it's not just those three units in the box; yes a lot of algorithms were ported over, but there's also a state-of-the-art amp and cab simulator, as well as an IR loader.

Best multi-effects pedals for guitarists: Line 6 Helix LT

3. Line 6 Helix LT

One of the best multi-effects pedals coupled with the best interface in town

Price: $1,199 | Number of effects: 104

Excellent user interface
Huge number of patches

If the HX Effects doesn't quite cover your needs - say, if you need amp modeling, or if you own a Line 6 Variax guitar - then the Helix LT offers all of the processing oomph of the full-fat Helix, but in a slimmed-down package without scribble strips or all of the inputs and outputs of the flagship.

Whether it's on-stage or for studio use, the LT is simply a beast, with great quality amps, effects, cabs, mic sims... you name it.

It's got eight assignable patches on the front panel, as well as bank change, tuner and tap switches and the best user interface of any multi-effect on the market, including Fractal Audio’s Axe-FX III, which is three times the price. What's not to like?

4. Fractal Audio AX8 multi-effects pedal

An upgradeable multi-effects pedal offering a huge selection of effects

Price: $1,299 | Number of effects: Loads! | Number of assignable footswitches: 11

Best-in-class effects
Studio quality tools
There’s a new model on the horizon

The Fractal Audio AX8 is packed with enough amp and speaker cabinet models and multi-effects capability to last most players a lifetime of exploration. It’s also packaged in a super-durable pedalboard controller and costs a fraction of the price of Fractal’s flagship Axe-FX III processor.

The selection of amp and speaker cabinet models is huge and includes almost every vintage classic and workhorse from the ‘50s until today. Same goes for the effects, offering instant access to pedal and rack processor effects that would take a lifetime and a fortune to accumulate. 

Internal memory stores 512 presets, but you also can save additional presets via the AX8’s USB interface when connected to a computer.

Best multi-effects pedals for guitarists: Headrush Pedalboard

5. HeadRush Floorboard

The best multi-effects pedal if amps are more your thing

Price: $999 | Number of effects: 34 | Number of assignable footswitches: 8-10

If you want amp modeling as well
If you care most about overdrives
If you’re after wacky sounds
The touchscreen isn’t great

With a huge amount of processing power on offer, the distortions on the HeadRush are really something to write home about. Drives have rich higher-order harmonics and plenty of headroom, interacting in a startlingly amp-like way with the on-board amp models and performing excellently when being used to boost a real-life amp in the room.

Though the HeadRush has the normal array of effects you'd expect - vintage delays and choruses, modern versions of the same effects and some stereo variants - there's nothing truly outside-the-box here. If you're looking for wilder, space-cadet sounds, then - unlike with the Boss and Line 6 units - you'll have to look at expanding to at least a couple of extra pedals alongside this floorboard.

Also, though it looks good on paper, the touchscreen is often more annoying to use than a regular joystick or arrow keys.

Best multi-effects pedals for guitarists: Mooer GE-300

6. Mooer GE300 multi-effects pedal

A powerful and compact multi-effect with a decent user interface

Price: $799 | Number of effects: 164 | Number of assignable footswitches: 4-8

Great range of effects
Synth effect is fantastic
Other options at this price
Weird footswitch layout

After a decade slugging it out at the lower end of the market with their distinctive micro-effects, Mooer has changed tack, and recently started releasing ambitious digital pedals. 

The GE300 is its flagship unit and, fully loaded with excellent effects and a fantastic monosynth patch, it certainly delivers the goods. Our only issue with the unit itself is that by default the footswitches have the assigns on the second row, which seems a bit backward compared to competitors.

The other problem with the GE300 is that Mooer's success is built on them being highly price-competitive. As with the Ocean Machine, its Devin Townsend signature pedal, the company's gone upmarket with the GE300 and there’s a price tag to match. The GE300 is a serious piece of kit, but it's hard to recommend it over the Helix LT when they're both around the same price.

7. Zoom MS-70 CDR

The best multi-effects pedal for creating unusual sounds

Price: $129 | Number of effects: 86 | Number of assignable footswitches: 1

Massively customizable
A bit fiddly to use

A sleeper hit in some corners of the online pedal community, the Zoom is deceptively deep. Powerful enough to keep up with any single-pedal sized digital effect, yet versatile enough to take the place of a multi-effect in a pedal chain, the MS-70 models a variety of vintage and modern boutique effects within a tiny, stereo enclosure.

Its real power is being able to use six of its effects simultaneously in a chain, allowing for very expressive and unusual sounds to be created. Best of all, since it's so small, even if you only use those sounds in one song on the setlist, the MS-70 doesn't take up much space!

Best multi-effects pedals for guitarists: Tech21 SansAmp Fly-rig 5

8. Tech21 Fly Rig 5

If you want a simple solution and don't want digital effects

Price: $329 | Number of effects: 5 | Number of assignable footswitches: 0

If you like (mostly) analog effects
Compact form-factor
Not very flexible

The Tech21 isn't quite an analog option, but for multi-effects it's about as close as you can get. Although it's possible to make analog delays using old-school 'bucket brigade' chips, reverb effects require digital processing, and as a result the Fly Rig 5 is a hybrid unit.

Still, Tech21 knows how to make a fantastic drive, and the Fly Rig 5 boasts a Plexi SansAmp and a boost, meaning it can be used in front of an amp or straight into a powered PA for maximum flexibility. 

The delay and reverb are solid, if nothing to write home about - the real selling point here is how tiny this little beast is. If you don't require more than a simple delay and reverb besides drive options, then this is one of the best multi-effects pedals out there, especially as a back-up or - as the name suggests - fly rig.

Best multi-effects pedals for guitarists: NUX MG-300

9. NUX MG-300

Killer amp-modeling tones, drums and looping in a compact, budget package

Price: $149 | Number of effects: 32+ | Number of assignable footswitches: 2

Easy user-friendly interface
Outstanding next-gen sounds
Editing patches is super intuitive 
Construction isn’t super rugged 

The out-of-the-box sounds of the MG-300 are seriously impressive. Its simple user-friendly design with expression pedal, tactile controls, push-buttons and a color screen is easy to navigate - you’ll barely need to crack open the manual. The MG-300 doesn’t overwhelm you with too many features either. It packs only the necessary garden variety of desirable amp models and classic effects – all of which are fantastic in tone and feel – along with 25 built-in cabinet IRs that combine four classic microphones with three positions, while you can also load third-party IR files via NUX QuickTone edit software for added versatility. 

This pedal’s audio modeling secret weapon is the TSAC-HD (True Simulation of Analog Circuit) algorithm, which delivers studio-quality guitar tones that actually sound authentic and dynamic compared to other modelers. Add in 56 built-in drum beats and a 60 second loop function, and the NUX MG-300 punches impressively above its weight for price, portability and sound.
