About The MG-50LI
Our flagship multi-effects processor and amp modeler for guitar and bass, delivering pro-grade tone in a compact, stage-ready design.
Featuring TS/AC-4K physical modeling and DeepImage profiling, it captures the authentic amp feel with stunning realism. With stereo cab simulation, advanced routing, and up to 14 simultaneous effects, the MG-50Li is built for practice, recording, and live performance — all with intuitive controls, Bluetooth, a USB-C audio interface, and app-based editing.
Advanced Amp Modeling
TS/AC-4K modeling algorithm recreates 30 legendary amps at the component level for unparalleled realism.
DeepImage Profiling
Proprietary multi-layer capture process allows for better, more nuanced reproduction of amps and overdrive pedals.
Block‑Style Effects & Routing
14 independent movable signal blocks cover all effect types, and allow for multiple of the same effect type in a single or split chain.
CyberIR Cabinet Simulation
Choose from over 30 factory cabinets for extensive tweakability, or load up to 120 of your own IRs to make it your own.
5-Hour Battery Life
Play around your presets on the fly and never worry about limited outlets or ungrounded power at your gig.
NUX Audio Editor Support
Edit amp models and effects, manage presets, load IRs, and configure USB‑C routing for recording or streaming on your computer.
Our Most Powerful Multi-Effect Yet.
Triple NXP® RT DSP Processors
The MG-50LI features our most powerful Whitebox modeling yet!
This led us to design a new hardware platform that uses three of our proprietary DSP processors: (1) one dedicated to handling all effects, (2) another to run the amp modeling algorithm, and (3) the third to support the split amp simulation functionality.
What does this mean to you?
Better sound quality
Amp modeling, cabinet simulation, and effects each run on dedicated processing, resulting in clearer tone, richer detail, and more accurate dynamics.
Get tube-like response when playing
Instead of producing a flat or static digital tone, the MG-50Li’s powerful amp engine reacts dynamically to your playing, much like a real tube amplifier.
Run more effects at once
You can run up to 14 simultaneous effect blocks without sacrificing performance or audio quality.
Get the fastest pedal response
Dedicated processing power for complex processes means that the MG-50LI operates fast, smoothly, and reliably.
Consistent performance live
Even with complex signal chains, the MG-50LI remains stable and responsive, making it reliable for stage and studio use.
Future-ready design
Dedicated DSP headroom allows for firmware updates and new features without compromising performance.

What does this mean to you?
Enjoy 60+ high-quality modeled amps
Amp models ranging from true classics to iconic and legendary well-known amps are accessible with a single stomp!
Control modeled amps as if they're real
Allows you to adjust virtual components of the White-box models (gain, EQ, etc.), just like the original modeled amp.
More realistic cabinet tone
CyberIR™ models how speakers, cabinets, and microphones interact, resulting in a more natural and three-dimensional sound than static IRs.
A Profiler Like No Other
DeepImage® Profiling
Our proprietary black-box amp profiling technology lets you capture the real sound and character of physical gear (like amps, preamps, overdrive/distortion pedals, etc.) and load that captured tone directly into the MG-50Li’s amp block for use anywhere in the signal chain.
Learn how you can capture your gear with the NUX IMAGE App.
What does this mean to you?
Add & capture your own amps & pedals
DeepImage® lets you record and save exact tonal snapshots of your favorite amps and pedals and recall them anytime.
Blend Profiling with Modeling
The MG-50Li doesn’t treat profiling as a separate feature. You can combine your profiles with NUX’s internal modeling engine, EQ models, and selectable power-amp tube types for deeper tone shaping.
Get Tones for Days
Up to 14 effect blocks to play with!
Also, the way you connect those blocks isn’t fixed!
Instead of forcing everything into a single straight line, the MG-50LI lets you use both serial and parallel routing paths, so you can build more creative, flexible, and professional signal chains.
It even lets you add the same effect type in a single chain multiple times!

Precise, Intuitive Controls
The MG‑50LI combines a large full-color LCD, dedicated knobs, and footswitches with a built-in expression pedal, letting you edit presets, tweak effects, and switch scenes effortlessly.
Extensive Hardware Connectivity
With flexible inputs and outputs—including instrument, stereo L/R, send/return, aux, USB, headphones, and expression pedal—jam, record, or perform live exactly the way you want.
Unlock the Full Potential of Your MG-50LI
With the NUX Audio App, you can fine-tune patches, load custom IRs, update firmware, and manage your entire MG-50LI library directly from your phone or computer.
NUX Audio App Features →
Faster Editing & Visual Clarity
Instead of navigating small screens or multiple menus on the floor unit, you can see the full signal chain, blocks, IRs and amps at once on your computer.
Real‑Time Interaction
When you tweak the physical knobs or effect parameters on your pedal, the NUX Audio App reflects those changes in real time — giving you visual feedback for what you’re doing.
Preset Organization
Helpful for players who switch many presets for gigs, rehearsals, or studio. The app gives you more room to organise than the pedal alone.
Block Routing Control
The NUX Audio App lets you easily reorder signal blocks (amps, effects, IRs), giving you flexible control over how your signal chain is structured.
IR & Amp Model Management
Since the MG-50LI supports third-party IRs and seed models, the app gives you a more convenient way to manage and load custom content and fine-tune offline.
USB Routing Configuration
The NUX Audio App supports different USB‑C audio routing modes, like NORMAL, USB Loopback, REAMP, and DRY OUT
Backup & Safety
Helps you create backups of your patches, so you’re less likely to lose your settings if you update firmware or change hardware setups.
