BEST VALUE MODELLER

The NUX MG-400 is a value packed modeller 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 modeller for the money.

[TSAC-HD]

WHITE-BOX AMP MODELLING

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

The White-box Amp Modelling & 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!

L STAR

512 samples IR resolution and USER slot with each patch.  (additional 12 IR COLLECTION slots)

IMPULSE RESPONSE

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

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!

NG, CMP, EFX, AMP, IR, EQ, MOD, DLY, RVB, P.L | 10 independent moveable signal blocks.

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.

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.

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, re-amp, and even do live-streaming with the MG-400.

In Normal mode, you can choose Loopback to play the playbacks from PC when doing a live stream.

zelda‘s “indoor” ⚽️ ball!
Color: Squeaky Green, Size: Medium Size 2 (6")
zelda loves her soccer ball - because of the fabric “tabs”, and the way she treats her toys, we keep it inside. she loves to place all of her toys and bones on our bed, after they’ve been cleaned. this ball is perfect and soft enough to throw it down our steps, where she will run down, retrieve it, and bring it back to the bed. it arrives deflated and comes with the pump and two needles - the pump is not the sturdiest and felt like it was not inflating, but after only having to reflate it once with a bit of air since receiving it ~5-6 months ago, it still holds up!

Small for a medium
Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

Fun and engaging toy that keeps dogs entertained.
I bought this smart interactive dog ball and it has been a fantastic toy for keeping my dog active and entertained. As soon as I turned it on, the automatic movement, bouncing, and rotating immediately caught my dog’s attention. My dog loves chasing it around the house and yard, and it keeps him busy for a long time. It’s a great way to help dogs burn energy, especially on days when they can’t get as much outdoor exercise. The material feels strong and durable, and I like that it’s made from food grade rubber, which makes it safer for dogs that like to chew. The size is perfect for medium and large dogs, and the light feature makes the toy even more exciting during playtime. The ball moves unpredictably, which keeps dogs curious and engaged. Another feature I appreciate is that it’s waterproof, so it’s easy to clean and can be used both indoors and outdoors. Overall, this is a great interactive toy that provides mental stimulation and physical activity for dogs. I highly recommend it for pet owners who want a fun way to keep their dogs entertained.
