Generally speaking, effects aficionados fall into one of two categories. On one side, we have the players with the carefully curated pedalboards full of an always-evolving rotation of vintage and modern stompboxes. This is often the group constantly chasing the zenith of perfect tone, trying to find that inspiring blend of organic circuitry that transcends their sonic capabilities.

The second group is comprised of the players who tend to skip the pedalboard and opt for a multi-effects unit. Instead of single, dedicated circuits for each of their effects in the form of stompboxes, they choose the digital models of the multi-effects processor. In return, they receive many more effects in one package, often with the ability to save specific user-created combinations and the ability patch sounds from the web.

As dedicated gearheads, it is the promise of endless possibility that ignites our curiosity and fuels us to consistently try new things. Whether you’re already kneck-deep in multi-effects processing or are interested in dipping your toe into a new world, check out our list below for some of the best multi-effects pedals under $400.

Tech 21 Fly Rig 5

The Tech 21 Fly Rig 5 is a great choice for stompbox lovers who are just getting into the multi-effects game or want to streamline their pedalboard setup.

Weighing in at just over a pound and under a foot in length, the board is super compact and will easily fit into most guitar cases or a backpack. The board emulates a stompbox feel with five stompbox on/off switches controlling Tech 21’s Boost DLA delay, SansAmp, Boost RVB reverb, and Hot Rod Plexi distortion/overdrive.

The Boost DLA delay section offers a tap tempo, a drift feature (a modulation sort of like a chorus), repeats, and time. The SansAmp preamp does feature amp simulation which would allow you to plug into a DI for an amp sound if you decide not go through an amp. It also allows you to dial-in your sound regardless of what you’re playing through, which can be especially useful if you’re playing through a house amp rather than your own. This section offers a three-band EQ, a reverb, and a drive feature as well. The Plexi section provides you with a Marshall-esque overdrive and a 23 decibel boost – enough to cut through any mix.

This multi-effects pedal is a streamlined, bread-and-butter solution that severely cuts down what a gigging musician would need to carry to a general gig.

Boss ME-80 Guitar Multi-Effects Unit

The Boss ME-80 is another multi-effects unit that packs an impressive punch. The board itself features stompbox-style knobs and eight footswitches, as well as a volume/expression pedal.

It’s packed with 59 effects featuring loads of Boss’s signature stompboxes – overdrives, distortions, wahs, reverbs, pitch-shifters, modulations, and more – that you can tweak with the knobs just like on a genuine stompbox effect.

You also get nine guitar preamps, and the pedal uses GT-100’s COSM modeling to simulate amps. It comes equipped with a 38-second phase looper, Boss’s Multi-Dimensional Processing (featured in their Tera Echo and Multi-Overtone pedals), and USB audio interface connectivity that allows you to do all of your tweaking with Boss’s Tone Studio software directly in your DAW.

As an added bonus, you get web connectivity with Boss Tone Central which is a library full of free patches you can download to use and modify yourself.

Line 6 M9 Stompbox Modeler

The Line 6 M9 is perfect for a player who plays in multiple bands that span multiple music genres.

Instead of having to lug around multiple pedalboards or constantly change out your chain for each different gig (or even each song), the Line 6 M9 gives you the ability to create six separate and unique pedalboards directly on the interface. You can also backup your pedalboards onto your computer via MIDI in/out, so you’ll always have your carefully crafted combos.

With 75 effects to choose from, you should have no trouble pairing the right sounds for each of your pedalboard scenes. You can use each effect individually or use up to three effects simultaneously with three more ready for action behind them. The board is packed with all of Line 6’s classic stompboxes, and you can tweak any effect directly on the board with knobs (like a genuine stompbox) rather than having to navigate complicated menus.

If you’re a stompbox who prefers pedals of the boutique variety, you might be wondering if there’s any multi-effects unit that would suit your tastes.

Digitech RP500 Multi-Effects Switching System & USB Interface

If you’re not looking to spend very much on a multi-effects processor, the Digitech RP500 is the choice for you. You can pick one up for as little as $175 used, and you can often a new unit for around $200.

Even though this is our budget option, it still packs a wide array of features. It features 20 banks, five separate stompbox footswitches, and an expression/volume pedal that controls the volume, the built-in wahs, and the Whammy effect. It comes with a total of 200 presets – 100 factory and 100 user-generated. It features 40 tone and 40 effects libraries with over 125 effects including classic stompboxes, delays, choruses, amps, and cabinets.

Digitech also offers over 400 free patches on their website that you can download for even more sonic capability. This pedal gives a lot of credence to the “a lot for a little” tagline.
