The NuX MG-400 Dual DSP Multi-FX Modeling Guitar and Bass Processor 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 and 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

It features the same amp modeling algorithm as MG-300, for easy tone tweaking, the White-box Amp Modeling and Pre-Efx algorithm offers realistic playability and analog-chaos response. The concept of Chaos makes the muse perfectly applies to the analog 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

The MG-400 includes multiple impulse responses 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 an electric guitar to simulate acoustic guitar sound with acoustic guitar IRs.

10 Independent Flexible Blocks

There are ten independent flexible blocks - NG, CMP, EFX, AMP, IR, EQ, MOD, DLY, RVB, P.L. 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 the gain stage to create grooving riffs. There are lots of tone creations with flexible block routing.

2.8-Inch 320 x 240 Color LCD with Intuitive UI

An intuitive user interfaces 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 and Looper

The MG-400 supports NUX Phrase Loop Synchronization with Rhythm. You can play the rhythm and 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

The NR Normal Recording mode works as a regular loop function, while you press CTRL1(LOOP) footswitch, it starts to record the phrase loop whereas the Auto Recording mode 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.
