With USB-C connectivity, it doubles as a high-quality audio interface compatible with PC/Mac editing software.

## Description

NU-X | MG-400 Guitar Multi-FX Pedal Core | Image Modulation, Delay and Reverb Effects With Fully-featured drum machine and looper The NU-X MG-400 builds on the success of the ground-breaking MG-300 compact multi-FX pedal, adding dual processors and delivering high definition models and increased flexibility. Integrated effects sections include Drive, Amp Simulation, I.R cabinet simulation, Modulation, Delays & Reverbs with a host of options within each category. Audio modelling is based on the NU-X TSAC-HD algorithm, which delivers high definition analogue circuit simulation for pro quality guitar tones. An expression pedal covers wah and swell effects amongst other possibilities. All settings can be edited onboard or via USB using the downloadable PC/Mac Quicktone software and then stored into one of 36 internal memory locations. For live or rehearsal backing, the built-in Jam function has a fully featured drum machine and phrase looper. To integrate with a DAW studio suite, the USB also functions as a high quality audio interface, completing the studio-ready guitar rig. The main output can be stereo or mono for guitar amplifiers or D.I to studio equipment. There is an additional 3.5mm output for stereo headphones. Expanding the control surface has provided space for additional control footswitches for a smoother and more accessible live playing experience.

Review: Excellent sound quality & tones. - Great bit of kit excellent presets.
Review: Doesn't recreate authentic tones but lot's of effects included. - Sounds are fizzy rather than authentic tones. Easy to tweak sounds on a laptop or pc using software. Some alternatives are available this price. (reviewing some months later...... Having had this for over 6 months now I'm not impressed by this pedal. I've downloaded the relevant software and firmware and tweaked constantly. None of the sounds are useful to me. As I said, a bunch of effects but poor sounds on the whole. Distortion fx and compressor all simply push the sound to unpleasant grittiness. Clean sounds are still brash to my ear. I have many pedals and amplifiers including some these sounds are meant to model. Ok, it cost less that £200. I maintain it's to unauthentic sounding for practical use.

### ⭐⭐⭐⭐⭐ Excellent sound quality & tones.

### ⭐⭐⭐⭐ Amazing range of effects. Even better when connected to a laptop
*by R***E on 7 November 2024*

The Good: Easy to save and modify effects. Screen is good and tells you what you need to know. Nice compact size and good range of outputs (stereo out and headphones are very handy) The Not so Good: Volume pedal isn't great (limited range) but it works. Probably not the ideal unit for live gigs but if you can get your head around the functionality, you'll be fine.
