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.

Inexpensive walls.
Color: Grey, Size: 34" - 3 Panel, Color: Grey, Size: 34" - 3 Panel
We had a hot request for a workstation in the warehouse with some privacy. These have worked great. Easy to assemble. They are lightweight and stable. This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.

Smooth, Stable, and Perfect for Flexible Spaces
Size: 88''W-4 Panel, Color: Grey, Size: 88''W-4 Panel, Color: Grey
This room divider is incredibly easy to move thanks to its industrial-grade silent casters. It glides smoothly across different floor types with just one hand and without any noise, while the built-in wheel locks keep it firmly in place once positioned, no slipping or unwanted movement. The base with reinforced steel feet adds impressive stability, preventing wobbling even in busy or high-traffic areas. I also love the foldable design, which makes storage effortless when it’s not in use. It folds down compactly and fits neatly into small spaces. I gave only 4 stars because I'm not crazy about the color of the fabric. Otherwise this is a very functional way to separate areas.

easy to put together, stable and blocks out unwanted eyes.
Size: 88''W-4 Panel, Color: Grey
If you live in a high rise building, or where there is lots of foot traffic and can see in your windows, this is a must have. It's portable, can fold down one or two walls and easy to move around. Put together once, and block out light and eyes while tall enough to see over. You can fold it up along the wall, and use it to block out the blinds or light when using a projector so that it's darker. You can use it to partician the room if you share one, and separate your pile of junk from your room so you don't look at it, can take quite a bit of towel weight and clothes and doesn't tip over. Sturdy bottom metal and easy to put together. I got the grey one, and glad I did. I use it everyday and is part of my room decor. I love it, and after using it for a few months it's quite durable. The quality is there for sure. A tad pricey, but worth it. Must have for a private person.

Well made dividers.
Size: 88''W-4 Panel, Color: Grey
Very durable and stable. Once positioned, they stay upright and firm and don't wobble around. Good materials on both the panels and the frame that supports it. Great for any partitioning needs and a fair price for the quality you receive. Highly recommended.
