In recent years, multi-effects pedals have solidified themselves as a popular choice among hardware modeling enthusiasts, and they’re more sonically and functionally viable than ever before. They’re often used as top-to-bottom tone generators—from effects chain to amplifier to speaker cabinet—for recording guitar directly to an interface, practicing through headphones or studio monitors, and performing live with a signal sent straight to FOH. Floorboard-style units can also be integrated with real amps, substituting expansive stompbox layouts for a standalone, streamlined effects processor. No matter how you choose to apply it, these are some of the best multi-effects pedals available for guitarists and bassists.

What Is a Multi-Effects Pedal?

Amp and effects simulation dates as far back as 1982, when Scholz Research & Development, Inc. (SR&D) released the Rockman—a speaker-less, portable cassette player-sized practice amplifier for guitarists, complete with clean, edge-of-breakup and distorted modes, alongside switchable reverb and chorus. It initially offered guitarists an easy means of playing through a pair of headphones or a stereo receiver, forgoing loud, expensive tube amps and clunky signal chains. Years later, in 1998, Line 6 launched their original POD amp sim and multi-effects processor, helping establish the blueprint for modern modeling as we know it. Today’s best multi-effects pedals certainly build on the foundation laid by those early predecessors, with an unbelievable amount of power compared to the old-school units.

Here, we’ll be looking specifically at floorboard-type processors that combine stompbox-style functionality and the extraordinary flexibility of a contemporary hardware modeler. Each entry on the list provides onboard guitar amp and cabinet emulation as a primary feature, as well as a huge selection of both vintage and modern effects. So, whether you’re looking to dial in a tight, percussive tone for extended-range metal, create a droning ambient soundscape or duplicate a timeless signal chain for country, blues, rock and more, these all-inclusive pedalboards have you covered.

Its user-friendly color touchscreen streamlines patch making, and each memory may contain up to two amplifiers and 15 simultaneous effects for as much or as little depth as your tone requires. BOSS’ AIRD modeling technology is second to none, delivering the rich, nuanced sound and feel of real tube amps. Hard rock and metal guitarists will especially appreciate the X-Ultra, X-Optima and X-Titan high-gain amp models, meticulously crafted with the latest, greatest BOSS emulation technology. The GX-10 is also filled to the brim with over 170 effects, including numerous BOSS classics, as well as various gain stages, modulation, reverb, delay and even bass-specific “pedals.”

What’s more, the BOSS Tone Studio companion app is an intuitive way to create, edit and organize presets from a computer.

Start with one of 100 preset memories, or dive into the deep end of patch design, using the built-in touchscreen and four rotary encoders to quickly and intuitively manage all operable parameters. Elastic internal routing lets you run amps and effects in series or parallel for unlimited sonic variation, and you can save up to 200 of your top settings for instant recall on stage or in the studio.

The ME-90’s dedicated amp section contains 11 AIRD models, noted for their tube-like tone and touch response. Choosing from 60 onboard BOSS effects in every category, the ME-90 lets you stack up to seven simultaneous sounds after the amp block to dial in your own presets—save up to 36 of your favorites, or hit the ground strumming with 36 preloaded factory tones for immediate inspiration. When you run the board in Memory mode, you can use the footswitches to change full patches on the fly. In Manual mode, switches can toggle individual effects for stomp-style operation.

It’s a great idea to download the free BOSS Tone Studio app for Mac/PC, where you can edit patches and gain access to even more effects connected to your computer over USB-C. All considered, the ME-90 is simply a great deal, as you’re not paying for a big color display.

Why Choose a Multi-Effects Pedal Over Amps and Stomps?

Multi-effects pedal processors are hard to beat in terms of cost and convenience relative to “real” amps and stompboxes. For less than the price of many tube heads/combos, you can equip yourself with dozens of emulated amplifiers and effects—all housed in one portable processor. Plus, you can run a multi-effects unit with a power amp and speaker cabinet to retain much of the traditional playing experience and still enjoy the nearly endless tonal possibilities modelers offer. And when it’s time to jam or practice quietly, record right to your DAW or play a fly date with a barebones rig, a hardware amp and effects simulator can do that, too.

Even if you run a modeler in front of your favorite amplifier for its effects alone, you can easily create complex signal chains that would require handfuls of physical pedals. Being able to engage presets, or patches/scenes, containing multiple effects with one footswitch is a massive modeling advantage. With regular pedals, this would require a complex switching system and a lot of wiring/programming know-how—or a professional consultation and buildout. Multi-effects pedals put everything you need at your feet and fingertips.

In a similar vein, the effortless routing flexibility of modelers has most standard rigs on the ropes as far as intuitiveness and speed are concerned. You can quickly swap effects in and out, and change your virtual pedal order, to experiment with textures at will—no physical repatching necessary. Not to mention, you can alter your amp platform from searing American high gain to classic British crunch to vibrant old-school cleans at any time. The best multi-effects pedals are some of the most versatile tools guitar and bass players have at their disposal.
