Best Value Modeler

The NUX MG-400 is a value packed modeler akin to his little brother, the MG-300. MG-400 houses 2 powerful DSP chips for high-definition White-Box Amp Modeling algorithm (TS/AC-HD) and Core-Image post-effects. Since releasing the MG-300, people have been blown away by the sound and playability, not to mention the ease-of-use tone tweaking and intuitive interface. And now, the MG-400 builds upon the MG-300 feature set moveable signal blocks, 12 IR COLLECTION slots, flexible P.L block with MIN & MAX parameter setup, abundant SYSTEM MENU, and physical MASTER volume knob, MG-400 is now the best value modeler for the money.


[TSAC-HD] White-Box Amp Modeling

Same Amp Modeling Algorithm as MG-300, for easy Tone Tweaking:

The White-box Amp Modeling & Pre-Efx algorithm offers realistic playability and analog-chaos response. The concept of “Chaos makes the muse” perfectly applies to the analogue circuit. When you tweak the knob, it affects itself as well as other parameters. For a linear digital system, the parameter is independent. The white-box algorithm offers real-time feedback, increment-by-increment. NUX TS/AC-HD replicates the same playability most guitarists crave in a real tube amplifier.

2 more amps have been added in Firmware V2.1.1!


Impulse Response

512 samples IR resolution and USER slot with each patch. (additional 12 IR COLLECTION slots)
The MG-400 includes multiple impulse response of 512 samples each. You can load 3rd party IR files using our NUX QuickTone edit software (support up to 48kHz sample rate). The included 25 guitar cabinet IRs combine 4 classic microphones with 3 mic positions to allow beginners a quick and easy way to jump into the multi effects experience. Also included are 8 bass cabinet IRs and 3 acoustic guitar IRs, giving you the ability to play bass guitar on MG-400 or use electric guitar to simulate acoustic guitar sound with acoustic guitar IRs.


10 Independent Flexible Blocks

NG, CMP, EFX, AMP, IR, EQ, MOD, DLY, RVB, P.L - 10 independent moveable signal blocks.
You can move signal blocks freely on the MG-400 and/or QuickTone editing software. Set the PATCH LEVEL block in front of AMP to swell the volume. Put DELAY block in front of gain stage to create grooving riffs. There are lots of tone creations with the flexible block routing.
Since Firmware V2.1.1, you can hold the signal block to switch: CMP<–>EFX , EFX<–>MOD , MOD<–>EFX, RVB<–>DLY. Therefore you can stack 2 Delays at the same time, or stack the CMP or 2 EFXs (OD/DIST) at the same time!


2.8" Color LCD

2.8" 320x240 color LCD with intuitive UI. An intuitive user interface with a colorful LCD lets you get rid of reading manuals. Keep it Simple!


Jam (Drum & Looper) Perfect for Playing and Singing

The MG-400 supports NUX Phrase Loop Synchronization with Rhythm. You can play the rhythm then record your phrase loop. MG-400 will automatically beat match the phrase to fit the current rhythm BPM.

Choose either STEREO / MONO looping. (Stereo is 30 seconds, mono is 60 seconds.)- Two Recording Modes

• NR = Normal Recording works as regular loop function, while you press CTRL1(LOOP) footswitch, it starts to record the phrase loop.
• AR = Auto Recording will stand by while you press CTRL1(LOOP) footswitch, once you hit the strings, it will start to record your phrase loop.


QuickTone Editor Software

You can download the QuickTone editor from the MG-400 product page. An intuitive interface is provided for tweaking parameters, dragging block order, setup SCN, save patches, load patches, export patches, load IRs, set up USB routing and CTRL SETTING; all by simply using QuickTone.


USB Audio Interface

For home studio and silent practice, the MG-400’s USB audio capabilities makes it the Swiss Army Knife of guitar audio interfaces. Connect it via USB to your PC, and you can record tracks, reamp, and even do livestreaming with the MG-400.

In Normal mode, you can choose Loopback to play the playbacks from PC when doing a live stream.
Re-amp: MG-400 offers Dry Out and Re-amp recording applications.

Best Purchase for my room
Color: White
I was skeptical at first but I’ve been using it for about 2-3 months, and it runs every day at 6am and it has never failed me. It always has a full filter at the end for the week, and the app is very good. When it would get stuck in places, it would always find a way out and I’ve never had to manually fix it. What’s even better is that there are 100-300 dollar roombas out there and yet this one has outperformed the expensive ones. They even are going to send me 4 free filters and 4 free brushes just for using it daily.

Doesn't last
Color: White
This product was working well. I used it daily but all of a sudden after 8 months it just stopped charging. I wish it actually lasted because it was a great product. But since it now no longer charges its of no use and a waste of money smh

Amazing little robot with roller mops - Eufy has come a long way
Upgraded from an old Eufy unit that would bounce around all the objects in my house at random and did a mediocre job, and needed to be emptied daily due to the amount of dog hair, not to mention detangling the thing daily as well. But worked ok while we had it. This unit has been an enormous upgrade, not only does it not get stuck on every sock in my house, but it actually mops my floors! My wife didn't think it would make that big of a difference but it's been a huge lifesaver and quality of lifesaver especially. Even with all the dog hair the unit anti-tangle brush does an excellent job with maintenance one to two weeks to perform some basic detangling which is much easier to do now as well given the parts and how they come apart. Personally I like the proprietary detergent, it seems to be going a long way, and I know it's the perfect amount for what the unit needs which means less work for me when I need to refill the water tanks. Also the scheduling features are nice in that it can vacuum daily and mop every few days since I don't need that done daily. My only feedback so far that would be negative at all are 1) there is one particular spot in our house at my standing desk where the robot gets stuck on occasion. It seems like it could be fixed easily with a software update to avoid climbing over something that it can't get down from. 2) The water tanks are not sealed at the top so you can't set them down once you fill them or else you'll spill water everywhere. Makes it kind of inconvenient to work with, but knowing that makes it easy to avoid. 3) the find my robot button is hidden deep in the app it should be one of the first things you see. When it got stuck somewhere it took me longer to find the button than it did to find the robot.

Arrived covered in water, brush errors when trying to run
Unit came completely covered in water. Minimal care taken with this "like-new" unit, had been leaking water into the plastic bag. Even with that, I gave it the benefit of the doubt and still finished setting it up. Within the first 30 seconds it was already reporting an error with one of the brushes. They would barely spin, stop, and fail. Even after thorough cleaning, the error persisted. The unit also struggled to find the home dock even when placed next to it, eventually erroring out as well. Given how many issues this had within 5 minutes of opening the like-new box, I returned this for a refund.
