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.

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.

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” 320*240 color LCD with intuitive UI.

An intuitive user interface with a colorful LCD lets you get rid of reading manuals. Keep it Simple!

SCENE FUNCTIONALITY

Use SCENES to engage/disengage blocks with either CTRL footswitch.

You can assign CTRL1 or CTRL2 to trigger the SCENE Functionality. Each preset has 3 scenes, which are snapshots within a preset. This is a powerful function for live gigs. Each SCENE can engage/disengage signal blocks freely, and it retains the DELAY / REVERB trails when you disengage them with SCN CTRL.

Jam ( Drum & Looper )

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.

Quick Tone 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.

nice set
Color: Clear Black
I bought this set to organize a messy desk drawer and it made a huge difference right away. Having multiple sizes in one pack is what really makes this set useful. I was able to customize the layout instead of trying to force everything into a few fixed compartments. The trays feel sturdy enough for everyday use and the clear design makes it easy to see everything at a glance. I used them for things like pens, paper clips, chargers, and random small items that usually get lost, and now everything actually has a place. They also don’t slide around much once placed, especially if the drawer is fairly full, which I appreciated. Setup took just a few minutes and instantly made the space look cleaner and more put together. If I had to note anything, the plastic is lightweight, so it is not heavy duty, but for organizing office supplies it works perfectly fine. Overall, a really practical set that helps you stay organized without overthinking it.

Great organizers!
Color: Clear
This is a really practical organizer set. I used it in my bathroom and nightstand drawers, and it helped clean everything up fast. The different sizes are the best part—you can mix and match depending on what you’re storing. Only reason I’m giving 4 stars is because the plastic isn’t super heavy-duty, but it’s still perfectly fine for everyday use. Good value for the amount you get.

Nice drawer organizers with a lot of versatility.
Color: Clear
I bought these to organize my desk drawer because it seems like I can never find anything I'm looking for without taking everything out first,which is always a pain,so I thought why not try a set of drawer organizers.Talk about night and day,these things keep all my stuff tidy and easy to find now,it's great! The plastic doesn't feel cheap either and the different sizes are very versatile,they also come with enough rubber feet for all the containers,though you do have to peel and stick them on yourself,but it's easy and the adhesive feels very strong. I would definitely recommend these if you're looking for some great containers to get things more organized.

Easy to configure. So helpful!
Color: Clear, Color: Clear
My house has old bathroom cabinets that are too narrow for most organizers I have found. These organizers come in different sizes so I can mix and match the pieces to fit the drawers and items I have to store. I have filled two drawers with these and still have more containers to use. These are truly the tool for the job. They are sturdy, stable and I thought I would have trouble with them moving around but they stay in place while maintaining their versatility. If I need to switch out stuff, I just reconfigure the drawer. No assembly required. One of my most favorite simple purchases. I can’t believe I have lived without these simple but helpful organizers!

Great for lip gloss. Headbands. Little toys and trinkets for preteen
Color: Lilac
This set is great! I love the colors, and my daughter is obsessed with anything purple — light purple, dark purple, all of it 💜. She uses these for all her little trinkets like keychains, Q-tips, headbands, braces, hand sanitizers, little toys, and lip glosses. They’re easy to use, easy to clean, and great quality. She’s had them for a few months now and they’ve held up really well Different sizes. They like up for accessibility
