ALM MFX Pedal ()
ALM's cult-favorite Eurorack effects now come in a stompbox you can take on stage. It has 18 algorithms and MIDI, and it's built like a tank.
Overview
The ALM MFX module is a Eurorack effect that does everything from Lexicon-style reverbs to glitchy, time-warped delays, all in 6 hp. ALM has now put that same digital engine into a pedal, their first stompbox. It isn't a straight clone. It's a rethink of how those deep, studio-grade effects can live outside the rack. Guitarists, synth players, and DAWless performers can get the same sound without a Eurorack case, CV expertise, or a cheat sheet taped to the pedalboard.
This isn't a guitar pedal trying to be "modular adjacent." It's a full transplant. The MFX Pedal carries the same 18 algorithms that made the Eurorack version a favorite for end-of-chain texture and ambience, with hands-on control for live use. There are two assignable knobs, a tap-tempo switch, a bypass footswitch, and an expression pedal input. It slots into a guitar rig, a synth effects loop, or a mixer send, and it can process anything from basslines to vocals to full stereo mixes. It works with both instrument and line-level sources.
The enclosure is new anodised aluminium and compact at 4.92" x 2.56" x 2.76". It has stereo inputs and outputs, plus a small display with a data wheel for navigating presets and parameters. It retains all settings when powered off, so no patches get lost between gigs. You can save user presets for each algorithm, tweak parameters on the fly, and assign controls to MIDI, knobs, or expression. It rewards digging in, but you can still dial in a sound fast.
It isn't a Boss GT-100-style multi-effect with amp sims and 500 presets. It's more focused and more surgical. The algorithms are modeled after classic hardware like the Ursa Major Space Station and Alesis QuadraVerb, pulling from DSP technologies spanning the 70s to today. Some users report the delays are especially strong, "refreshingly different" from typical stompbox fare, and the overall sound quality is consistently described as top-notch. Early adopters have also noted quirks. Some of the drive algorithms introduce hiss at high gain (though nothing out of the ordinary). The mix control also has a known behavior: any setting above 0% cuts the dry signal's volume. That's not a flaw per se, but it has to be accounted for when blending effects.
The 5-pin MIDI input supports CC messages 1-4, so parameters can be automated from a controller or sequencer. Clock sync is also supported, so delays and repeats can lock to tempo. In early firmware, some users have reported MIDI bugs. They're not dealbreakers, but they suggest the implementation isn't fully polished. Anyone building a tightly synced live rig might want to wait for a firmware update or test thoroughly first.

Key Features
DSP Power from Eurorack, Now in Pedal Form
The ALM MFX Pedal is a repackaging of the MFX Eurorack module, renowned for its depth and variety, in a format that doesn't require a modular system. It has the same 18 algorithms that Eurorack users have praised for creating "long lush controlled ambience textures without chaotic self-oscillations." They aren't only reverb and delay clones. They span decades of DSP development, from vintage emulations to modern, glitch-heavy processing. Some are directly inspired by hardware like the Ursa Major Space Station and Alesis QuadraVerb, without the bulk or price tag.
The level of control sets it apart from most multi-effects. Each program offers a wide range of parameters that can be assigned to the two front-panel knobs, MIDI CC messages, or an expression pedal. Sweeping a filter in real time during a performance is a matter of assigning it. Syncing a delay repeat to tempo is handled by clock control. The interface is meant to be familiar and quick, with no menu diving under stage lights. The small display and data wheel make navigation easy, and all states are preserved across power cycles, so it can be unplugged, thrown in a case, and picked up where it left off.
Live-Ready Control and Flexibility
For stage use, the tap-tempo footswitch sets delay timing on the fly. The true bypass/DSP bypass options let you choose between signal purity and feature retention, like maintaining trails. The stereo I/O keeps wide mixes wide. The optional analogue gain stage adds more tonal shaping and is useful for driving signals into the effects with more grit.
The expression input accepts standard passive TRS pedals, so it isn't locked to a specific brand. It can also take a 0-3V CV source, bridging the gap between pedal and modular worlds. That makes it a natural fit for hybrid setups, say a guitar feeding into the MFX with an external sequencer sending CV via a passive split. USB-C on the back handles firmware updates, so ALM can refine the unit over time and potentially smooth out the MIDI quirks that early users have reported.
Not Just for Guitarists
It's housed in a pedal format, but the MFX isn't trying to compete with the Line 6 Helix or Zoom MS-70CDR. Reviewers have openly questioned whether guitarists will embrace it, given the crowded multi-effects market. The MFX Pedal is just as much for synth players, electronic producers, and anyone running a DAWless setup. It excels at processing stereo synth outputs, drum machines, or vocal tracks sent from a mixer. You don't need to be a Eurorack owner to get these sounds.
Historical Context
The ALM MFX Pedal was first presented at Superbooth 24, where it drew attention as ALM's debut in the pedal market. Until then, the MFX name was known only in modular circles, where the Eurorack version had gained fame for its wide variety of effects and efficient 6 hp footprint. The pedal brought ALM's signature processing to a much broader audience of guitarists, live performers, and studio engineers who might never build a modular system. It reflects a growing trend of boutique modular manufacturers expanding into more accessible formats.
Collectibility & Value
As of May 2024, the ALM MFX Pedal retails for about $370 / £319 / €380. Given its newness, there's no established secondhand market yet, and no data on common failures or long-term reliability. Early user reports highlight both strengths and quirks. The sound quality is consistently praised as "top notch," with delays and reverbs standing out. The depth of the 18 algorithms is considered impressive, offering far more than reverb and delay. Some users have noted that the mix control reduces dry signal volume at any setting above 0%, which could be a workflow issue for those relying on subtle blending. A few have reported MIDI bugs in early firmware, so it may benefit from updates before being trusted in critical live setups. There's no information on repairability or maintenance, but the anodised aluminium enclosure suggests a build quality that should withstand road use.
