Amp Profiling and Cloud Features
NAM A2-Lite Native Support
Updating to firmware V1.1.1 adds support for NAM (Neural Amp Modeler) A2-Lite Native profiles. This allows for far more flexible importing of external tone files and profile data.
Cloud Integration via NUX AUDIO
Using the dedicated NUX AUDIO ecosystem, you can back up presets and system parameters directly to the cloud. It also lets you upload and share custom presets online, streamlining sound management across different devices.
Enhanced Workflow and Control Features
Interface Refinements
On the preset screen, Knob 2 is now assigned to adjust preset volume. Screen readouts display values from +12 dB to -12 dB, giving you precise visual control when balancing output levels between presets.
Footswitch and Global Setting Upgrades
- STOMP LATCH Control: Adds LATCH control in STOMP mode for more responsive footswitch effect toggling.
- EXP / CTRL Sync: TAP and SCENE settings are optimized to apply across all three footswitches (S1, S2, S3) at once, streamlining setup.
- Extended Delay Times: Maximum delay time when using TAP Tempo expanded up to 2000 ms (equivalent to 30 BPM).
- Patch Tail On/Off: A Patch Tail toggle added to global settings lets you decide whether delay and reverb trails spill over or cut off when switching presets.

Community Reaction Map
Reactions are split between some finding the price higher than expected and others excited by the dual-amp routing per patch. Players who have hands-on experience report a slight learning curve, factory presets heavily drenched in effects, and around 6 hours of battery life from the internal lithium cell.

Pricing & Comparisons$499 feels steep to some, but a fraction of top-tier modelers to others
I was checking daily to see if it finally became available... (lol) I was just about to buy a Hotone Ampero 2 or Stomp when this came along... I really hope the price is in line with Hotone's flagship multi-FX... (lol)
Unfortunately, it came in pricier than I hoped. $499. I think I'll just stick to getting a Hotone Ampero 2 Stomp.
I think people are missing how much you get for this price point. Sure, it doesn't reinvent the wheel, but it's definitely the first unit offering this at nearly a quarter of the price of the competition. I've wanted to get into amp modeling for a while, and this brings it within budget. Planning to run this into two Boss Katanas for an awesome stereo hybrid rig for just over $1,000.
So if Nu-X, Mooer, and Hotone can build almost the exact same unit for half, a third, or a quarter of the price of a Quad Cortex or Line 6 Helix Stadium, does that mean consumers are just paying extra for the brand name on high-end units?
Sorry everyone, but these discussions lack substance. Even after watching the video, I still can't see what a $1,000+ multi-FX offers over a $400 NUX. Is it just prejudice against "cheaper" gear? Here's an idea—why not debate Rob Chapman, who seems fully behind this unit?
Dual Amps per PatchDual signal paths with splitter routing for separate TRS and XLR outputs
Two amps in a single patch? Finally! This definitely caught my attention!
What you want to do is totally doable and pretty straightforward to set up. When building a patch, you get 3 signal chain options. Selecting the last option places a splitter at the front, giving you dual outputs. Put your amp sim, IR, and pedals on the bottom path, and leave the top path empty (just like recording a dry DI track). The top chain goes to the TRS output, and the bottom to the XLR output. If you use the MG-50 expression pedal, place it before the splitter to control both chains.
Controls, Presets & Battery LifeRequires some learning, but hands-on scene creation is straightforward
Hope this helps: just got mine... first a few minor negatives (not many!): it's not quite as plug-and-play as influencers lead you to believe. It takes some getting used to. Unless you love super wet effects, most factory presets are pretty rough—nearly every patch is drenched in delay and reverb. The built-in lithium battery is a killer feature, lasting about 6 hours on a full charge. Once tweaked, it sounds great. I also own a Headrush MX5, which feels easier to navigate, so I'll probably keep that one around for recording over the MG-50Li.
This pedal is super easy to work with and sounds fantastic. Built a couple custom patches: one for funk with 3 scenes—a spacey Funkadelic vibe, a punchy Tower of Power feel, and an old-school James Brown / JBs style. Another for jazz with 2 scenes—subtle plate reverb and light delay for a cozy jazz club atmosphere, plus a second scene adding chorus for a Brecker EWI flavor. Awesome tool and very intuitive.
Summary
The NUX MG-50Li is a versatile amp modeler and profiler upgraded via Firmware V1.1.1 to support NAM A2-Lite profiles, cloud integration, and deeper control customization. Whether for studio recording or live performance, it offers flexible tone creation and streamlined operation in a single unit.
